I would give myself an understanding of status. Women are attracted to high-status (doctor, lawyer) and thus men spend time attaining status.
But status is affected by subcultures; if I spend 6-months learning how to write an NES emulator or speed-running N64 GoldenEye or reaching 2200 elo in chess -- I'll get status from a small group of gaming enthusiasts but in the larger context its (probably) not a good use of my time.
For example, I got a double major in unrelated fields (I was ambitious and wanted to signal how smart I was), but it would have been better had gotten straight A's and masters degree (a double-major only impresses 1st-year undergrads; in the larger context of academic status, its irrelevant).
Take risks, say yes to all opportunities, try to fail often.
I don't mean risks in the sense of things that put you physically or mentally in harm's way, but trying ideas, learning new things, new activities etc.
Some reasons: the explore/exploit tradeoff is massively in favour of exploring when you're young, you have almost nothing to lose, very few responsibilities and so much time (relatively speaking to later in life).
I have no regrets, since all mistakes are a lesson to learn from. You don't grow if you don't make mistakes. That doesn't mean I'm hap-hazard and do dangerous things, it just means I transmute failure/mistakes into lessons.
My twenties were experimental. I learned the ropes. I failed often and failed early. Now to inculcate those lessons into everyday life. This is like turning lead into gold.

It would also teach my younger self about counter-signaling in the status game https://host.kelley.iu.edu/riharbau/cs-randfinal.pdf
Also not too much alcohol and HIIT fitness.
