To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

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

If you've got a talent, protect it.

Know or listen to those who know.

Things do not happen. Things are made to happen.

I can, therefore I am.

If you think you can do it, you can.

It's always too early to quit.
