It's always too early to quit.
Well done is better than well said.
The most effective way to do it, is to do it.
Always desire to learn something useful.
Do not weep do not wax indignant. Understand.
After a storm comes a calm.
Without hard work, nothing grows but weeds.
What you do today can improve all your tomorrows.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
One reason the human race has such a low opinion of itself is that it gets so much of its wisdom from writers.
