To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
I can, therefore I am.
Never complain and never explain.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
Well done is better than well said.
