Be kind whenever possible. It is always possible.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
Never complain and never explain.
If you've got a talent, protect it.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
Know or listen to those who know.
Only the educated are free.
As man sows, so shall he reap. In works of fiction, such men are sometimes converted. More often, in real life, they do not change their natures until they are converted into dust.
There's time enough, but none to spare.
