I don't trust people who start businesses and say they're not interested in money. Money is one of your best gauges of whether you're doing things right. Not being interested in money when you're working on a for-profit enterprise makes me worry you're either unserious or disingenuous. That said, hardly anybody only cares about money. We all trade off money against other things -- free time, independence, and so on. I care about money, but I'd rather make a little less working on a project that'll genuinely make the world better than a little more working on something unimportant.
