There is a large banner at Evolve Academy with this quote on it, and I’ve heard it so many times there that I can never forget.

It’s a twist on the whole practice makes perfect idea, and it’s understandable since perfection is not possible.

What is possible though is habit formation. The problem there is that it can be difficult to control the habits that you are developing or break bad habits once you already have them.

This is one reason why it is so important to be pay attention to what you do every day because every activity is contributing to habit formation.

Now imagine that you wanted to be proficient in self defense so you went out and found a martial art to master. We can say Brazilian Jiu-jitsu because if you're not already training, you should be.

Obviously.

Anyway, so you’re diligently training every day, but doing the technique wrong. Now you’ve done this for some time and developed some bad habits.

Let’s say it took you 10000 repetitions to develop a bad habit, so now it will take 20000 repetitions replace that with a good habit.

So it should be clear how hard it can be to change a bad habit once formed. That is why it is best to never develop them in the first place.
