By failing to prepare, you are preparing to fail.

Never complain and never explain.

Know or listen to those who know.

To know oneself, one should assert oneself.

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

Without hard work, nothing grows but weeds.

If you think you can do it, you can.

If you're going through hell, keep going.

Things do not happen. Things are made to happen.
