Anger is a good motivator.

Fear is always a good motivator.

If you didn't have patents, no one would bother to spend money on research and development. But with patents, if someone has a good idea and a competitor can't copy it, then that competitor will have to think of their own way of doing it. So then, instead of just one innovator, you have two or three people trying to do something in a new way.

If you get stuck to the committed path then...
this wall has to be..
KNOCKED DOWN!!

Good time management is a major motivator, from my perspective.

Anger is good when it alerts you to danger, but bad when it hurts you and others.
