Expect problems and eat them for breakfast.
Wherever you are - be all there.
You never know what motivates you.
If you've got a talent, protect it.
The dog that trots about finds a bone.
Leap, and the net will appear.
Do not weep do not wax indignant. Understand.
The secret of getting ahead is getting started.
Well done is better than well said.
I can, therefore I am.
