To know oneself, one should assert oneself.

Never complain and never explain.

Either you run the day or the day runs you.

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

It's always too early to quit.

Do not weep do not wax indignant. Understand.

The dog that trots about finds a bone.

By failing to prepare, you are preparing to fail.

If you think you can do it, you can.
