Expect problems and eat them for breakfast.
If you're going through hell, keep going.
It's always too early to quit.
Go for it now. The future is promised to no one.
The dog that trots about finds a bone.

Wherever you are - be all there.
You never know what motivates you.
After a storm comes a calm.
Be thine own palace, or the world's thy jail.
Because at bottom, I'm interested in fear, and in courage and cowardice and these are easier to get at through fiction, where you can enter people's heads.
