The highest-ranking person in a company or other institution,
ultimately responsible for making managerial decisions.

"The critical ingredient is getting off your butt and doing something.
It’s as simple as that. A lot of people have ideas, but there are few
who decideto do something about them now.
Not tomorrow. Not next week. But today.
The true entrepreneur is a doer, not a dreamer.”
~ Nolan Bushnell
