If great companies were built by those exerting the least effort we would live in a very different world today.

The early histories of many successful SV companies are peppered with a sour business deal or two. The winners are those that hung on and fought. Did Gates walk away when when Jobs discovered that he was building GUIs? Who walked away from Facebook? Zuckerberg or the other guys? You know the twins...or "those other people" whoever they were. You get the point. Exactly, its just businesses.
