Be thine own palace, or the world's thy jail.

The dog that trots about finds a bone.

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

I can, therefore I am.

The wise does at once what the fool does at last.

It's always too early to quit.

If you're going through hell, keep going.

Do not weep do not wax indignant. Understand.
