Few things are as satisfying as acquiring a new skill, that is, being able to do something one could not do before. The sensation is all too gratifying, and sometimes proves wrong the judgment one made of the possibilities.

With practice and determination, wonders occur; and can hardly be equaled the satisfaction of looking back and seeing that, through one’s own efforts, it was possible to become capable.
