If you think you can do it, you can.
If you're going through hell, keep going.
Who seeks shall find.
Do not weep do not wax indignant. Understand.
You never know what motivates you.
It's always too early to quit.
Problems are not stop signs, they are guidelines.
Know or listen to those who know.
Never complain and never explain.
Leap, and the net will appear.
I sit down at my desk pretty early in the morning and write all day until about 4 or 5 p.m.
