I'd also strongly recommend spending a good portion on books. No Starch, Pragmatic Bookshelf and Manning are all great publishers. Books are so cheap there's no reason not to buy a dozen or more a year and refer to them only as needed.
Manning regularly runs 50% off discounts and I've gotten at least 20 No Starch books in Humble Bundles for even less. Pragprog discounts are rarer, but they're still a great value.
For the cost of a single US conference, you could literally subscribe to every screencast site I listed above, buy 25 tech books and still come out ahead.
Masterclass.com looks good too. Lots of non-code related things like writing and cooking by experts in their respective fields. Considering most of us don't know any professional actors or Michelin chefs, this is a fast way to pick up skills into the top 20% as cheaply as possible.
Plenty of books out there, but this is not the thread to list them.
Would it cover fitness? A personal trainer or dietician will take you further than most advice from friends and the internet.
I purchased 3 Masterclass (before they went recurring). The production quality is insane, but the content is closer to infotainment than education. I have no problem with infotainment and found the Chris Voss negotiation series helpful.
The James Patterson course is interesting (if you're a fan), but I didn't find it helpful at all for my writing.
