Jeff Cornwall, The Entrepreneurial Mind, is also thinking about success and failure:
Most highly successful entrepreneurs will tell you that along the road to success in their businesses they were often on the brink of failure. But they persevered. They found a way to make payroll. They found a way to make that critical sale. They found a way to keep the wolves away from the door just long enough to make it through the tough times. They found a way to pick themselves up from a business that did not succeed and move on to the next one that might.

We seem to have forgotten that failure, in fact, builds character. And it is the fear of failure that inhibits creativity and keeps us from learning.
