It's always too early to quit.
I can, therefore I am.
Go for it now. The future is promised to no one.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
If you can dream it, you can do it.
By failing to prepare, you are preparing to fail.
After a storm comes a calm.
I've been a teacher at the college level, in composition mostly, and I've been an editor on magazines.
