Peter F. Drucker Rule of Thumb

Successful entrepreneurs do not wait until "the Muse kisses them" and gives them a "bright idea": they go to work. Altogether they do not look for the "biggie," the innovation that will "revolutionize the industry," create a "billion-dollar business" or "make one rich overnight." Those entrepreneurs who start out with the idea that they'll make it big - and in a hurry - can be guaranteed failure.
