To know oneself, one should assert oneself.

If you think you can do it, you can.

Without hard work, nothing grows but weeds.

By failing to prepare, you are preparing to fail.

Never complain and never explain.

If you can dream it, you can do it.

I can, therefore I am.

Things do not happen. Things are made to happen.

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