Control d desire

Political tags - such as royalist, communist, democrat, populist, fascist, liberal, conservative, and so forth - are never basic criteria. The human race divides politically into those who want people to be controlled and those who have no such desire.

- Robert A. Heinlein

Another definition

All failure is failure to adapt. All success is successful adaptation.

- Max McKeown, Author and Strategic Adviser

- Edgar Allan Poe
