By necessity, entrepreneurs are self-delusional.

Most are easily intelligent enough to realize how long their odds really are. Furthermore, they have the intellect to appreciate the true effort they have to make before they reach financial payback.

Any reasonable person with the math skills to visualize risk vs. reward will usually walk away --but not the quintessential entrepreneur.

This is not a flattering trait. For this reason, it is rarely, if ever, associated with successful entrepreneurs.
