eh, I am in infrastructure, not science, but looking back, I have a really hard time coming up with something that I might have done (I mean, something that the person I was in my 20s would likely have done.) that could have caused me more financial damage than starting a company did.<p>On top of that, nobody tells you, but when you go to get a real job after starting a company? If you didn't have big-name VC, "Oh, that was your company?" the interviewer asks... but what the interviewer clearly means is actually "Oh, so you were unemployed"<p>I mean, I'm not saying that you shouldn't start a company, I'm just saying that you need to be mindful of the risks. Yes, you feel free when you are young, but any money you put into retirement then is extremely impactful. The same is true of anything you put into covering your long-term housing short.<p>Even if I could talk to myself in my early 20s, I probably could not talk him out of starting a company, but... i would be way better off now if he could have been talked into being more conservative... into maxing out all available tax-deferred retirement options, into limiting the amount of money and the amount of my self that I was willing to sink into the thing. Into buying a fucking condo, at least. Something.
