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

I can, therefore I am.

It's always too early to quit.

To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

The most effective way to do it, is to do it.

The dog that trots about finds a bone.

Be gentle to all and stern with yourself.

If you've got a talent, protect it.
