<i>Ultimately it comes down to the question of "exit". As a founder, I have no interest in exit or liquidity. I am in business to run a business, not to run away from it. Or as Warren Buffet puts it: Our favorite holding period is forever.</i><p>I often get the impression that many people in the tech industry have not internalized that it's possible to make a successful business (and a lot of money) without taking investment. Or that it may be desirable to run and grow a business over a long time period like decades.<p>While I don't have hard facts on this, I would expect that more entrepreneur wealth has been created through running businesses instead of exiting. Of the wealthy people that I personally know, this statement holds. But it seems reinforced regularly, for example with Gabriel's post yesterday analyzing how an entrepreneur would go about pocketing $5 million pre-tax on an exit.
