Someday my paintings will be hanging in the Louvre. [Vincent Van Gogh]
An artist would not rise above the mediocrity if he condemns it.
He who loves lives, he who lives works, and he who works has bread.
Talent is cheap; dedication is expensive. It will cost you your life.
Normal people do not create art.
You cannot be firmly certain about anything. You can only have enough courage and strength to do what you consider to be right. Maybe it turns out that was wrong, but still you would have done his, and it is most important.
