Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
If you can dream it, you can do it.
You never know what motivates you.
Well done is better than well said.
The wise does at once what the fool does at last.
Rewards and punishments are the lowest form of education.
Great wisdom is generous petty wisdom is contentious. Great speech is impassioned, small speech cantankerous.
