To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
Never complain and never explain.
Without hard work, nothing grows but weeds.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
Inconsiderate, rude behavior drives me nuts. And I guess the inconsiderate rudeness of social ineptitude definitely fuels my work.
