Unlimited Memory by Kevin Horsley Free Book Review Summary Audiobook Animated Book Summary PDF Epub on StoryShots


We view some people as having fantastic memories and others as having hopeless memories. However, the reality is that almost all of us only tap into 10% of our memory potential. Unlimited Memory aims to guide you to unlock more of that remaining 90%. Providing a wide range of concentration and memory methods, Kevin Horsley claims that readers can easily double their productivity and significantly enhance their memory.

“If you keep on doing what you have always done, you are going to get what you have always gotten. You need to do different to get different. Thus, a word of warning: mastering your memory is going to require a different kind of thinking.”

– Kevin Horsley

The Benefits of Having a Great Memory

A great memory gives you a distinct advantage by helping you to:

  1. Store and access more information quickly.
  2. Make mental associations.
  3. Build upon existing knowledge.
  4. Grasp opportunities.
  5. Increase your overall intelligence.

How to Improve Your Concentration

“We are training our brains to have an attention deficit. A lot of people simply cannot focus for an extended period of time anymore. I have heard that the average person looks at their mobile phone about 50 times a day. We are reading emails, the news, Facebook, and Twitter etc., during what should be family and relationship time.”

– Kevin Horsley

Kevin Horsley identifies concentration as fundamental to remembering anything. Without concentration, all other memory tips are pointless. Hence, he describes ways in which you can increase your concentration levels:

  • Rid yourself of conflict – Conflict can distract you from the task you are looking to engage. Examples of distractions are social media websites, games, or messages. However, it is not just distractions that impact on your concentration. Multitasking itself hugely impacts on your ability to concentrate. Kevin highlights that neuroscience research has found that multitasking slows efficiency by 50%.
  • Give yourself a purpose – If you have a purpose, your mind is less likely to wander. Kevin suggests that you adhere to the PIC rule. Purpose gives you a reason for learning (P). Ask yourself questions so you can become interested (I). Be curious (C) about what you’ve chosen to learn.

“You can remember mountains of information when you are interested in the subject. It almost feels automatic and your concentration is at a peak. Your deficits of attention are mostly interest deficits. Your mind never wanders away; it only moves towards more interesting and outstanding things.”

– Kevin Horsley

Creative and Fun Information Will Be Easier to Remember

Interesting and fun facts or information are always easier to remember. However, Kevin Horsley explains that personal creativity can bring any information to life. Hence, you can benefit from the memory-enhancing benefits of fun.

One way to attach fun concepts to information is by thinking of other similar words or noises. Kevin gives the example of pollo, which is the Spanish word for chicken. One way to remember this connection is by identifying that pollo sounds a bit like the sport of polo. Then, you can attribute humorous imagery to this idea e.g., think of yourself playing polo while riding a massive chicken. Making fun connections between words and visualizing them makes them far easier to remember.

“If your brain was unable to make images out of symbols, all learning and reading would be worthless and incredibly boring. Your brain likes pictures, and we are really good at remembering them.”

– Kevin Horsley

Kevin outlines a simple step-by-step approach to creating memorable and creative memory tools via the anagram SEE:

  1. Information enters our brain via our Senses. Therefore, it is crucial when imagining a word that we think of the textures and smells associated with the word. A multisensory image is easier to recall than a word.
  2. Exaggeration during visualization will make a word easier to remember. For example, say you need to remember the word ‘dolphin.’ It is considerably easier to remember a dolphin the size of a skyscraper that can glow in the dark.
  3. Energetic visual scenes are far more vivid in our memories. For example, a dolphin that is flying around a city is far easier to remember than a static dolphin.

Hence, the key to memory improvement is our imagination.

Sort Information Into Categories Already Stored in Your Long-Term Memory

Based on the lives we have already lived, we will have some categories stored in our long-term memory. For example, you might never forget the directions from your parents’ family home to your grandparents’ house. Alternatively, you might be able to recall every word from ‘Hey Jude’ by The Beatles. Either way, we all have some categories that are stored deep in our long-term memory. Kevin Horsley recommends that we utilize our strong memory traces for these categories and attach new information to them.

Utilizing pre-stored categories is an approach utilized by most world-record-holding memory experts. The specific type of approach they use is called the method of loci, also known as the route method. This method involves recollecting a route that you know exceptionally well. Then, you place the items you have to remember in specific locations along this route. These locations should be vivid and familiar. For example, a bright yellow house near your parents’ house is a good landmark. The key to this method is drawing connections between the item you seek to remember and the landmarks you travel past in your imagination. For example, suppose you seek to remember a hedgehog. In that case, you could imagine a hedgehog the size of the yellow house. The hedgehog should be sitting in the yellow house’s place.

As well as helping you remember the items, this approach should help you remember the order of the items. This could be particularly useful for certain circumstances. Remarkably, Kevin Horsley used this exact method to memorize the first 10,000 digits of the number Pi.

Use Sounds to Remember Numbers and Dates

Kevin Horsley also provides tips on how to remember numbers and dates. Remembering dates is often one of the most impressive features of somebody who has a good memory. We all know a friend or family member who always remembers the date that something happened. However, Kevin explains that there is a simple way to remember numbers that only requires three steps:

  1. Learn a system that changes numbers into letters. For example, the number 6 looks a bit like the letter g. Therefore, you can allocate the number 6 a sh sound. If you flip the number 3 on its side, it looks like the letter M. Hence sounds related to M can be used to remember the number 3.
  2. Subsequently, you should write down the letters that you have associated with the number you need to remember. Then, make up a word out of these letters. The author provides an example of the year 1969. 1969 is the year that humans first walked on the moon. With this date, you only need to remember the last three numbers. You can allocate these numbers the sounds b, sh, and p. Hence, it is possible to make the word BiSHoP. The vowels are unimportant for this method as our brain naturally fills those in anyway.
  3. Finally, you will want to picture the event you are trying to remember and the word you have just produced. In this example, it would be a bishop dancing on the moon.

Use the Four C System to Remember Names

“Have you ever heard people say, “I know the face, but I can’t remember the name…?” You never hear people say, “The face is on the tip of my tongue.” We remember faces because they form an image in our mind. The names don’t normally ‘stick’ because we try to remember it with our auditory memory or our little voice. It doesn’t make sense to try to stick a sound to a vision – of course it won’t stick. Plus, auditory memories are never as solid as visual memories.”

– Kevin Horsley

Arguably the most embarrassing thing to forget is somebody’s name. Kevin also outlines a method for making sure that you never forget a colleague’s name. The method is based on the four C system:

  1. Concentrate – Concentrate on the person’s name when they first tell you. Say the name out loud and then repeat it to yourself. If it is a tricky name, you should ask for the spelling.
  2. Create – Produce a memorable image associated with the person’s name by considering what items sound like the person’s name. For example, if the colleague’s name is Peter Bacon, you can imagine a man petting a piece of bacon.
  3. Connect – After creating a memorable image, you will want to connect this image to the person’s face you are trying to remember. One way to do this is by connecting a facial feature of the person to part of their name. The author gives the example of Janice with icy blue eyes. With this example, you would image Janice with icicles flying out of her eyes. Remember, exaggeration helps memory.
  4. Comparison – If you already know someone with the same name, it can be more challenging using these methods. However, you can then use the comparison method. You want to compare the face you already know to this one. For example, imagine both of these people’s heads on the same body chatting to each other about their similar facial features.

As well as adopting these methods, you must also make sure that you continue to use these people’s names. Additionally, having a list of names in your diary will help prompt your brain.

Consistently Review and Revise Information

Kevin testifies that these methods will improve your memory. However, it is still vital that you consistently review and revise the information you are seeking to remember. For example, Kevin states that people can only remember the equivalent of approximately three weeks’ worth of lessons from their entire school career. This effect is seen after just two years of finishing school.

The average person forgets 82% of what they have learned after 28 days. There is a specific way you should review and revise your information, though. Each time you revisit what you’ve memorized, the information becomes easier to remember. Therefore, help information transition from your short- to long-term memory by gradually leaving more time between one revision and the next. Plus, utilize consistent reviews to refresh your memory and deepen your understanding. Crucially, the first 72 hours are the most vital for remembering something. After that, you can review the information at progressively longer intervals. If you review something after 10 minutes, 1 hour, 1 day, 3 days, 7 days, 14 days, 21 days, 28 days, 2 months, then 3 months, you’ll probably remember it forever. This is called spaced repetition. Spaced repetition makes it more challenging to remember the information when you revise. Your memory for the concept will improve if it is slightly challenging each time you recall it.

Autopilot Breeds Forgetfulness

“We pay attention half-heartedly on almost everything we do these days. We live in an activity illusion and think that ‘busyness’ is equal to good business. Busyness is sometimes just procrastination in disguise. Busyness may make you feel good and make you think you are more productive. However, when we look back at the end of the day we realize we haven’t done anything worthwhile. We are training our minds to have continuous partial attention, and our attention is being fragmented.”

– Kevin Horsley

As well as adopting the techniques provided in Unlimited Memory, it is also integral that you avoid behaviors that encourage forgetfulness. For example, moving into autopilot leads to us entering a state of forgetfulness. Therefore, try to avoid the absent-mindedness often associated with daily life routines. Instead, be actively present in your mind. You can encourage activeness by asking yourself questions, telling yourself instructions, and being present in the moment.

Self-Belief Strengthens Your Memory

Self-belief is a crucial feature when developing your memory. You must create a reality where you fully believe in your true potential. If you believe in the potential of your memory, then you are more likely to apply attention and concentration toward memory tasks. Specifically, you will be better equipped to retain a clear mindset. You can also encourage productivity by remaining positive. If you have productive thoughts, then your actions will follow. Therefore, try surrounding yourself with motivating and empowering people and content.
