Be gentle to all and stern with yourself.

Expect problems and eat them for breakfast.

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

Things do not happen. Things are made to happen.

Begin to be now what you will be hereafter.

You never know what motivates you.

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

It's always too early to quit.

To know oneself, one should assert oneself.
