Life is both short and long. At 21 you’ll have so many opportunities to do your own thing going forward that it’s sort of silly for you to worry about it now, on the flip side, now is probably also going to be the time you have the least to lose.<p>I would normally advice you to go with what you feel is right for you, but right now, I’m personally going to be riding out the next few years as safe as possible. I think the world economy is in for its bumpiest ride in our lifetime. So unless the thing you plan on selling thrives in a market with a broken global supply chain, war in Europe, real climate impact, food shortages, political unrest and recession (and some things will thrive, they always do) then being a startup the next few years will probably be more of a challenge than it’s been for the past few decades.
