Be gentle to all and stern with yourself.

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

I can, therefore I am.

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

Either you run the day or the day runs you.

The dog that trots about finds a bone.

It's always too early to quit.

If you can dream it, you can do it.

To know oneself, one should assert oneself.
