Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
It's always too early to quit.
Always desire to learn something useful.
To know oneself, one should assert oneself.
Only the educated are free.
Never complain and never explain.
The dog that trots about finds a bone.
You never know what motivates you.
I can, therefore I am.
I do some of my best thinking while pulling weeds.
