Management is doing things right; leadership is doing the right things. - Peter Drucker

There is a point of complexity beyond which a business is no longer manageable.

The effective executive knows that it is easier to raise the performance of one leader than it is to raise the performance of a whole mass.

Entrepreneurs innovate. Innovation is the specific instrument of entrepreneurship. It is the act that endows resources with a new capacity to create wealth. Innovation, indeed, creates a resource. There is no such thing as a ‘resource’ until man finds a use for something in nature and thus endows it with economic value. Until then, every plant is a weed and every mineral just another rock.
