To know oneself, one should assert oneself.

I can, therefore I am.

Begin to be now what you will be hereafter.

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

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

What you do today can improve all your tomorrows.

Well done is better than well said.

Be gentle to all and stern with yourself.

Be kind whenever possible. It is always possible.
