Success comes when you focus on solving problems, not just making profits.
The more personal the art, the more universal it becomes.
Optimists tend to interpret their troubles as transient, controllable, and specific to one situation. Pessimists, on the other hand, believe that their troubles last forever, undermine everything they do, and are uncontrollable.
The artist's job is not to succumb to despair but to find an antidote for the emptiness of existence.
