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

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.

Either you run the day or the day runs you.

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

I can, therefore I am.

It's always too early to quit.

Begin to be now what you will be hereafter.

If you're going through hell, keep going.
