I’ve loved the below quote forever. It taught me a lot when I was studying music in college. Especially the line: “nothing is more common than unsuccessful men (or women!) with talent.”
“Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan ‘Press On’ has solved and always will solve the problems of the human race.” — Calvin Coolidge
