Never complain and never explain.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.

Always desire to learn something useful.

It's always too early to quit.

Go for it now. The future is promised to no one.

Be kind whenever possible. It is always possible.

Either you run the day or the day runs you.

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