Well done is better than well said.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

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

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

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.

I can, therefore I am.

Know or listen to those who know.
