It's always too early to quit.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
Well done is better than well said.
If you're going through hell, keep going.
Either you run the day or the day runs you.
Be kind whenever possible. It is always possible.
I can, therefore I am.
One doesn't have a sense of humor. It has you.
