So it appears that at the upper level of the need hierarchy, when one is self-actualized, money in itself is no longer a source of motivation but rather a measure of achievement. Money in the physiological- and security-driven modes only motivates until the need is satisfied, but money as a measure of achievement will motivate without limit. Thus the second ten million can be just as important to the venture capitalist as the first, since it is not the utilitarian need for the money that drives him but the achievement that it implies, and the need for achievement is boundless.
