I found an interesting article about Jeff Bezos, the founder of Amazon. I like it because it shows the early days where an entrepreneur shapes the company simply by overcoming one small challenge after another.  Often its not about making a huge plan to be exactly this sort of company but rather just using ingenuity to solve each crisis as it come along.  One day you look up and all the solutions add up to a pretty neat idea.  Another important point of this article is often the solutions did not come from the CEO in a vacuum, they came from his staff or from a brainstorming session.

Take a look, its worth the read.  Jeff Bezos: Birth of a salesman
