Well done is better than well said.
Never complain and never explain.
Problems are not stop signs, they are guidelines.
Know or listen to those who know.
Do not weep do not wax indignant. Understand.
Go for it now. The future is promised to no one.
I can, therefore I am.
It's always too early to quit.
Only the educated are free.
If you've got a talent, protect it.
All science is either physics or stamp collecting.
