It's always too early to quit.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

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

The dog that trots about finds a bone.

Who seeks shall find.

Do not weep do not wax indignant. Understand.

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

If you're going through hell, keep going.
