I have to remind myself that some birds are not meant to be caged. Their feathers are just too bright.

The time which we have at our disposal every day is elastic; the passions that we feel expand it, those that we inspire contract it; and habit fills up what remains.

"To be a writer is to sit down at one's desk in the chill portion of every day, and to write; not waiting for the little jet of the blue flame of genius to start from the breastbone."

If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.
