I can, therefore I am.

After a storm comes a calm.

If you can dream it, you can do it.

The secret of getting ahead is getting started.

Be gentle to all and stern with yourself.

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.

To know oneself, one should assert oneself.
