I believe all creative people come to a point where they doubt their ability. Some come to believe they can't go forward with their art one more day. They're quitting. Yes, the big Q word.
I certainly have.
~1887, the Musical Courrier: "Brahms evidently lacks the breadth and power of invention eminently necessary for the production of truly great symphonic works."
~ Confucius: "It does not matter how slowly you go so long as you do not stop. "
~ Unknown: "When the world says, "Give up," Hope whispers, 'Try it one more time.'"
~Harold Gould Henderson's translation of the Master Essa's "Snail, ever so slowly . . ."
"Snail, my little man, slowly, oh, very slowly climb up Fujisan!"
Any quotes that keep you going? Hope so. If not, take mine. I'm off to find Fujisan . . . and some fellow #writecampaign people at RACH WRITES.
