Ever since I was a child I have had this instinctive urge for expansion and growth. To me, the function and duty of a quality human being is the sincere and honest development of one's potential.
(Bruce Lee, martial arts expert and actor)
The only way to develop potential is by application. You cannot develop wisdom by just thinking about it, it's the act of doing that makes all of the difference in the world. Your character cannot ever become fully developed without the action of application.
