It's always too early to quit.
The dog that trots about finds a bone.
Know or listen to those who know.
To be a good loser is to learn how to win.
Well done is better than well said.
By failing to prepare, you are preparing to fail.
To know oneself, one should assert oneself.
Always desire to learn something useful.
After a storm comes a calm.
You never know what motivates you.
Thought is the original source of all wealth, all success, all material gain, all great discoveries and inventions, and of all achievement.
Do not trust to the cheering, for those persons would shout as much if you and I were going to be hanged.
