Definition of Marketing

I'm often asked to give my definition of marketing. In The Marketing Toolkit for Growing Businesses, I outlined what I thought was a very good definition of marketing. See what you think.

Do you agree with this definition of marketing:

"Marketing is a process where everyone in your company pursues actions, at designated contact points, to increase sales, grow profits and deepen relationships"

If not, what else is needed to round out this marketing definition?
