Seven years ago, a student came to me and asked me to invest in his company. He said, "I'm working with three friends, and we're going to try to disrupt an industry by selling stuff online." And I said, "OK, you guys spent the whole summer on this, right?" "No, we all took internships just in case it doesn't work out." "All right, but you're going to go in full time once you graduate." "Not exactly. We've all lined up backup jobs." Six months go by, it's the day before the company launches, and there is still not a functioning website. "You guys realize, the entire company is a website. That's literally all it is." So I obviously declined to invest.
