Be gentle to all and stern with yourself.

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

To know oneself, one should assert oneself.

Either you run the day or the day runs you.

The wise does at once what the fool does at last.

If you think you can do it, you can.

Things do not happen. Things are made to happen.

I can, therefore I am.

Begin to be now what you will be hereafter.
