How does this relate to OP? DMC is a highly talented person, but he's in his mid-40s, he's worked in the supposedly meritocratic startup sector (and, as with trading, the definition of success in VC-istan is making money; if you've been in VC-istan for 2 decades and haven't made fuck-you money, you haven't won) and his net worth (as he admitted on Quora) is less than $1m. Given that, it's fair to say that he probably hasn't played his cards right. That doesn't make him unskillful or weak or "a loser"-- far from it, and I'm sure that none of those are true. It doesn't make him any less of a person, or any less smart, than the more successful people. It just makes it a good bet that if he could rewind to 20 and play from there again, he'd have a lot more success.
And ultimately, the reason why many of us are sitting here not being rich and outlandishly successful when people of similar or inferior talent smash $500m+ exits is that, when faced with a thousand identical-looking doors, one with a pot of gold behind it, they had the "insight" to pick door #467 while we picked #822 or #134 or #915. Some of us pick #467 at the next opportunity but, of course, the next time the pot of gold is behind #719.
I think the best thing to do is to back away from the VC-istan insanity, and pretend all that garbage doesn't exist. As long as I'm growing my skillset by 20 to 25% per year (which is not hard to do, because returns from increasing skill in technology are exponential) I feel like I ought to be happy with that. It can be difficult to be satisfied with this (first world problems) when you see unqualified idiots getting funded in enormous amounts, and then getting acquisitions and EIR gigs as welfare checks because they have powerful friends... so it takes some discipline and maturity not to be annoyed... but sanity is worth it.
