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

This means that if we can do something we have to do that something and keep practicing till we get it right .In other words, this means to keep practicing things till we understand it by memory. Aside of this quote there is another that will help: "practice makes perfect." this should always kept in mind to keep moving forward and not getting slower. Example, if we want to learn on how to choose the right we have to choose the right in order to understand this concept.
