By doing it        

                     "We learn to do by doing" 

I think this quote means if you don't do anything, How are u going to learn anything? Spencer W. Kimball wants us to learn anything by doing it. If we want to learn anything, we have to do it like when we were little kid. People learns what to do when they just do it. Even our family wants us to learn things by doing it. If we want to learn anything like choosing the right than you have to do it to accomplished it. People out there must have do something to learn by building, working, cooking, and other things they did to accomplish it. If we want to become like them and learn anything, we have to do it.
