Be gentle to all and stern with yourself.
Only the educated are free.
It's always too early to quit.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
Well done is better than well said.
Who seeks shall find.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
I hate to play the I-live-in-the-country card, but it really takes all of the 'pack the kids into the car and run from here to there' out of the equation.
