Never complain and never explain.

Do not weep do not wax indignant. Understand.

If you can dream it, you can do it.

You never know what motivates you.

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

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

By failing to prepare, you are preparing to fail.

Always desire to learn something useful.

To know oneself, one should assert oneself.
