Never complain and never explain.

It's always too early to quit.

I can, therefore I am.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

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

The dog that trots about finds a bone.

Begin to be now what you will be hereafter.

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