It's always too early to quit.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
If you've got a talent, protect it.
To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
After a storm comes a calm.
I've tried word processors, but I think I'm too old a dog to use one.
