our brain is like muscles. the more you use and exercise it, the stronger it becomes. but, if you want to get maximum results, you should do more than just practice. what you need is deliberate practice. deliberate practice is the kind of practice that stretches the boundaries of your capabilities. while in normal practice you just do the same activity again and again, in deliberate practice you push yourself to the limit. it’s not easy, but deliberate practice makes the difference between an expert and everyone else.

　　the principle of deliberate practice can be applied in whatever field you want to excel in, but here i will focus on mind development. below are 8 ways to challenge and exercise your mind. choose some of them you haven’t done and take your mind to the next level:

　　1. read challenging articles

　　you can measure the difficulty level of an article by using google docs. here is how to do it:

　　create a new document

　　paste the content of the article to the new document

　　open the tools -word count menu item. it will show you three metrics: flesch reading ease, flesch-kindcaid grade level, and automated readability index. the higher it is, the more difficult the article is.

　　of course, it’s not necessary to measure the difficulty level of every article you read. simply take some samples from a blog or web site and you will have good idea about the difficulty level of the articles there.

　　2. read challenging books

　　classic books are good candidates since they are usually more difficult to read than new books. you could start with my list of classic books. you can also read the pulitzer-winning books.

　　3. read academic journals

　　one form of challenging reading we often overlook is academic journals. there are a lot of free journal articles you can read from open science directory. some of the journal articles in google scholar are also free. go there, pick a topic of your interest and read a journal article.

　　4. play mind games

　　choose a free mind game to play and you can have fun while exercising your mind. i started playing sudoku last week and it was more difficult than i expected. but over time my mind got used to it and i can now solve the puzzles faster.

　　5. aim to produce certain number of ideas everyday

　　the ideas can be in whatever fields you are working on. in my case, i try to write certain number of words everyday. q10 - which i first learned from dale - is an excellent tool you can use if you are a writer. one of its features is global target with which you can set the target number of words you want to write.

　　6. brainstorm using thinking tools

　　there are many thinking tools you can use. the book thinkertoys has many of them in one book and the web site exploratree has a collection of tools you can use.

　　7. do ultradian sprint

　　doing ultradian sprint is a good way to train your focus and concentration. one trait of a well-trained brain is the ability to concentrate for long time and ultradian sprint can help you increase your ability to concentrate.
