To know oneself, one should assert oneself.

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

Things do not happen. Things are made to happen.

Never complain and never explain.

Begin to be now what you will be hereafter.

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

Be gentle to all and stern with yourself.

I can, therefore I am.

Wherever you are - be all there.
