To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

I can, therefore I am.

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

Things do not happen. Things are made to happen.

It's always too early to quit.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

Wherever you are - be all there.
