Without hard work, nothing grows but weeds.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
If you've got a talent, protect it.
Know or listen to those who know.
Never complain and never explain.
The wise does at once what the fool does at last.
Leap, and the net will appear.
Words of wisdom are spoken by children at least as often as scientists.
