Quote 1 - - Erich Fromm

What are the necessary steps in learning any art? The process of learning an art can be divided conveniently into two parts:

• one, the mastery of the theory; 
• the other, the mastery of the practice. 

... ...

But, aside from learning the theory and practice, there is a third factor necessary to becoming a master in any art — the mastery of the art must be a matter of ultimate concern; there must be nothing else in the world more important than the art.
