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

Be gentle to all and stern with yourself.

If you can dream it, you can do it.

If you think you can do it, you can.

I can, therefore I am.

You never know what motivates you.

To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

Things do not happen. Things are made to happen.
