By doing it

"We learn to do by doing"

This quote is saying that whatever you do you have to learn how to do it in order to do it correctly and the way you want it to be. People always do stuff there way and want it to be perfect. Sometimes it turns out to be good but sometimes it doesn't come out the way they want. In order to do something you should know how to do it and to know how to do it you should learn first. Either you do it your way or another way. As long as you get it your way and your fine with it then it's good. If you do stuff the wrong way you won't be pleased with what you have or do because it didn't come out the way you wanted it. For example, if you want to learn how to play soccer and you do it on your own it would work out and the way you like to play. If someone else teaches you and you don't like how they are or they don't teach you the right way then you won't learn as well as you would yourself. When you learn something and you are willing to complete it then you will be happy with what you have and do.
