Be gentle to all and stern with yourself.
Well done is better than well said.
The dog that trots about finds a bone.
The secret of getting ahead is getting started.
Expect problems and eat them for breakfast.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
To know oneself, one should assert oneself.
Do not weep do not wax indignant. Understand.
If you know you are on the right track, if you have this inner knowledge, then nobody can turn you off... no matter what they say.
