There're a few big skills, both of which are really about mindset and worldview than anything else:
One is to recognize and embrace impermanence, and to do so as a way of inoculating yourself against sunk-cost fallacies. So for example, I put in a lot of work to learn Python, Django, and web development when I got out of college, and then to learn C++, scalability, and optimization while I was at Google. When I left Google, I had the idea to do an API-compatible reimplementation of Django where all the framework bits are written in tightly-optimized C++. But as I started evaluating that idea, I looked around and realized a.) Django was no longer the preferred way to build webapps b.) The web, arguably, was no longer the preferred technology to build apps at all and c.) users of Django either didn't care about performance or they'd gotten to be big sites that can afford massive AWS bills. Sucks to be me. Better to recognize that early before sinking a lot of work into that project. I've still got those skills (though both Django and C++ are moving targets), and they came in handy when testing and rejecting the following couple startup ideas.
A second skill is to view learning as rewarding for its own sake, and something that you do lifelong rather than just when you're young so you can get a job. I'd internalized this pretty well as a kid.
A third is to pay attention to people around you, and when they're doing something seemingly stupid, ask yourself why they're doing it rather than immediately judging. And a fourth is to pay careful attention to things that disconfirm your previous hypotheses.
As an example of both of these - when I first heard about Bitcoin in 2013, I read the whitepaper, mentally filed it under "Distributed database; might spawn 2-3 interesting companies but won't go anywhere else", and then forgot about it for a few years. When the bubble hit in 2017, I was like "Pyramid scheme. Actually double pyramid scheme, which is kinda clever. Wait for it to burst."
But then from that assessment comes a hypothesis - when I looked in detail at the ICOs being funded, I should expect to see 100% scams. I only saw roughly 35% scams, plus another 50% that were well-meaning teams who were in well over their head. With over 6000 ICOs being done, that's hundreds of projects that might actually have a chance of being something real. So while the vast majority of crypto projects are scams, there's still something very interesting going on, and perhaps its younger boosters may be onto something.
