Leap, and the net will appear.
Begin to be now what you will be hereafter.
Only the educated are free.
Do not weep do not wax indignant. Understand.
The dog that trots about finds a bone.
Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
Know or listen to those who know.
It's always too early to quit.
