Know or listen to those who know.
To be a good loser is to learn how to win.
Only the educated are free.
It's always too early to quit.
Who seeks shall find.
Do not weep do not wax indignant. Understand.
Go for it now. The future is promised to no one.
If you've got a talent, protect it.
Leap, and the net will appear.
Quality is not an act, it is a habit.
The capacity you're thinking of is imagination without it there can be no understanding, indeed no fiction.
