Perhaps also something on alternative income streams. I managed to work 24/7 on a startup once, but after it crashed and burned with nothing to show for it, I don't think I can do it again. I tried many times but I couldn't make it work.
AI would be more lucrative to work on but even though I have a degree labelled such, I find the chasm to a job making more money from that somehow impassable. But maybe it's not entirely.
I've had good luck with just throwing a set amount of each paycheck into the top crypto (mostly bitcoin and ethereum, lately more solana) with an auto-buy and not worrying whether it goes up or down. If it goes down, I just end up getting more coin for my purchase. Rode the last crypto bear market down like that, and a few years later (now) it ended up paying off big time.
Was super easy, didn't even have to think about it. Been trying to pay more attention this time around and it might not have been worth all the extra time and mindspace, honestly, except if I had started watching InvestAnswers six months earlier I would have put a big bet on Solana when it was ~$8 and been semi-retired by now, probably.
