Never complain and never explain.

Be gentle to all and stern with yourself.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

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

Either you run the day or the day runs you.

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

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.
