To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

I can, therefore I am.

Either you run the day or the day runs you.

If you're going through hell, keep going.

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

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

What you do today can improve all your tomorrows.

Well done is better than well said.
