Be gentle to all and stern with yourself.
Know or listen to those who know.
I can, therefore I am.
After a storm comes a calm.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
It's always too early to quit.
If you think you can do it, you can.
Either you run the day or the day runs you.
Without hard work, nothing grows but weeds.
Our learning ought to be our lives' amendment, and the fruits of our private study ought to appear in our public behavior.
