I can, therefore I am.

Things do not happen. Things are made to happen.

What you do today can improve all your tomorrows.

Never complain and never explain.

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

If you think you can do it, you can.

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

Be kind whenever possible. It is always possible.

The secret of getting ahead is getting started.
