"We learn to do by doing" - Spencer W. Kinball 

What Specer is trying to say is that we learn to do thing by actually doing them. for example if your trying to learning how to play basketball you really have to put effort to actually do it. Also if your tryingto learn to do something actually do it. you learn to do things by actually doing it. forexample i have to practice alot in order to learn how to play basketball i hjave to actually do it and put alot effort. and if you make a mistake and you're trying to change then the only way to change is by doing it. you have to learn to do things in order to be something. you learnbefore you do it. always learn to do by doing it.
