Intelligence is flexible and there are a lot of things to give it a daily boost. For smart thinking your mind needs 3 things:
To be trained in thinking processes
To have plenty of information
To focus on a problem or idea
For example, Thomas Edison was able to think of his light bulb because:
He was a trained logical thinker
He knew a lot about electrical engineering
He focused on solving a problem
Here are a bunch of things to do every day to help your mind to think smart.
1. Drink 2 glasses of water within 30 minutes of waking up
Since you’ve been asleep for hours, your body has not gotten water for 6-9 hours. Water is needed for the filtration of waste products and fluid balance. Two big glasses of water offset the fluid deficit you had from sleeping. Studies on kids (study 1, study 2) show that drinking more water increases their ability to complete mental tasks. Make sure your brain is not dehydrated at the beginning of the day already.
2. Read a book summary during breakfast
Reading books is great, but breakfast is far more suitable for something shorter. Instead of reading news articles that have little impact on your life/intelligence, read best selling book summaries. You can find summaries by:
Googling your book title + summary, for example “7 Habits of Highly Effective People summary”
Use a summary subscription like Blinkist or getAbstract
3. Listen to stimulating podcasts/audiobooks during your commute
Even if you spend only 10 minutes on your bike like I do, load your phone up with intellectually stimulating audio. Good sources could be:
TED talks (their app lets you pre-download audio so you don’t eat your mobile data)
Blinkist has some of their summaries in audio form
Audiobooks you purchased
Podcast of your favorite authors
4. Drink green tea while working
Where caffeine makes many people anxious, green tea (especially Matcha tea) contains l-theanine. This aminoacid causes an increase in alpha brain waves in the brain:
In practice this means that where coffee can induce anxiety, high quality green teas cause a relaxed focus without inducing sleepiness. This is also why l-theanine is available as a supplement to aid in relaxation and increasing cardiovascular health.
5. Take naps during the day
Napping helps your mind refresh. It’s been shown that napping during learning increases learning speed. Your mind has a rhythm that determines when it gets sleepy and when it needs sleep:
As you can see on average people feel more sleepy than usual between noon and 4 PM. This is a perfect time to have a nap, and will increase your alertness and productivity for the rest of the day. Personally I’ve has good results with post-workday naps too (around 6 PM).
6. Don’t take sugar during the day
In fact, if you can cut it altogether. But if you can’t for whatever reason, just make sure not to have it during times where you need to focus. Sugar highs and the following lows are not good to keep your brain functioning smartly. What does work very well are fatty acids. Try to switch any sweet stuff during lunch for something more substantial like fish or eggs.
7. Do social media / meme websites only a couple of times a day
The brain adapts to the information you throw at it. If you bombard it work non-stimulating and fast switching information your focus will get destroyed. Keep your brain functioning on a higher level by throwing stimulating things at it. If you feel the need to procrastinate, set a timer and don’t get lost in mindlessly scrolling.
8. Play games instead of watching series or movies
Watching tv is a passive activity. Your brain is consuming information, but not processing or interacting with it. Substitute or supplement this entertainment with gaming. A 2014 study showed that even a simple game like Super Mario has visible impact on brain plasticity (flexibility). Another piece of research covered by Forbes shows the same. Actively engage your brain where you can, instead of letting it slumber passively.
9. Read a book instead of watching tv
Similar to playing games instead of watching tv, reading a book is an active exercise for the brain. Where watching video entertainment is a passive consumption of information, reading a book requires your brain to actively construct mental images of what you are reading.
10. Do some programming
Programming is a great way to learn to think logically and in patterns. Coding used to be hard to learn but with free websites like Codeacademy and free/paid platforms like Udemy it is easy and fun to learn. Consider it the next level of puzzles. As an added advantage learning to code in your free time increases your employability in the job market.
11. Watch TED talks while cooking
Preparing dinner is a great time to catch up on some cutting edge developments in Technology, Education and Design (ted.com). It turns what would otherwise be downtime into a fascinating and stimulating block of time. It’s like watching the news, only you are watching the world’s most inspiring individuals talk about their work.
12. Do some simple exercises during the day
The body and the mind are strongly connected. Physical fitness helps the brain function well. You don’t however have to go to the gym every day to benefit from this (though you can of course). Doing some push-ups throughout the day and walking or skipping up some stairs has a great impact already. Try to do something physical every hour or so, even if it’s just getting up, stretching a little and tensing all your muscles as hard as you can for 5-10 seconds.
13. Spend time with someone smarter than you
Habits are socially contagious. It is a well known fact in science that obesity for example spreads through social networks (link to research). The habits and thinking patterns of those you spend time with rub off on you. Expose yourself to people who are smarter than you in order to benefit from them.
14. Talk to people who disagree with you
Get into (friendly) discussions with people who disagree with you on any topic. Arguing with them allows you to either:
Sharpen your arguments
Be convinced that you are wrong
In both cases you win. In the first you convince the other person by out reasoning them, and I the second false logic you previously had is not eliminated.
15. Go for a walk in nature
Walking through nature has a number of benefits:
There is more oxygen since plants produce it
The human mind calms down when surrounded by plants
Walking helps your blood circulation
Having a walk in a park at lunch time can greatly help you work smartly for the rest of the day.
16. Carry a notepad
Great minds like Leonardo Da Vinci always carries a notepad. They used it to jot down ideas, sketches and questions they had for later review. Having a little book on you and writing down interesting things can greatly help you train your curiosity and logical thinking.
17. Take 10 minutes at the end of the day to plan tomorrow
By planning tomorrow the day before you begin the day with a plan. This allows you to work much more productively. Many people are busy all day, but not actually productive. A great part of being smart is knowing that hard work is inferior to smart work. Pick your battles in advance.
