I can be both afraid and courageous at the same time.

The two aren't alternatives. One is the precondition of the other. Doing something you found easy was never courage; it was just an errand.

Which means the shaking hand holding the phone before a call you've put off for six days is not evidence against you. It's the required equipment. Whatever gets done in the next four minutes will be done by a frightened person, and that is the only way anything difficult has ever been done.
