I’d add to presentation skills: negotiation skills. I’ll recommend Chris Voss’ book “Never Split the Difference” as I have been to all my relatives this Christmas.
"It is taken as established that the NSCA had a commercial motivation for making the false statement in the Devor Study (…) that the NSCA made the false statement in the Devor Study with the intention of disparaging CrossFit and thereby driving consumers to the NSCA (…) (and) that a loss in CrossFit’s certification revenue was the natural and probable result of the false injury data in the Devor Study."
Trust me it REALLY depends on the box and the coaches...there's 2 coaches that aren't super helpful, but they're still nice and friendly, but the owner, and 2 of the other coaches are amazing.
At 515, you can't do a ton, so they walked me through modifications, they give me extra help to get better form, they slow me down when I want to push past my limit or feel I'm not progressing fast enough -- so I don't get injured.
Heck, they even call and fb chat w/ me if I miss a class. I started 9/10 @ 515. It's 12/27 and I'm 430. Goal is be <300 by 2020 (40th birthday).
I can see CrossFit REALLY sucking if quality isn't there, and the coaches suck, I don't like going to classes AS much when the good coaches aren't coaching, so I think that's the difference..
A normal gym you just have equipment, quality doesn't matter that much, in CrossFit --it's all about the people running the place, if they aren't attentive to those who might need extra help getting up to par, then find a different box.
This business of exercising for the sake of exercising for the rest of your life as if it is some sort of cross to bear is not the best technique to staying healthy! Try and enjoy it.
OP list is the young mans guide to SV future reality if I had to guess.
As for written communication, Markel's Technical Communication was used in my English class in college and I remember getting a lot out of following its directions. As you might expect, it's very well written. Of course, I had the advantage of classroom instruction, but I think it would be helpful even for self-study.
Never Split the difference from Chris Voss is a good book. Persuasion and negotiation are also as much about effective listening. Something I've practiced hard this year is to be mindful of creating a pause before I respond. Pause for like 2 seconds.

Forget stock picking, it is generally a fool's errand.
Also - Tony Robbins did a good job with his book "Money: Master the game". Look up the "All weather strategy" from Ray Dalio referenced in that book. Diversification across non-correlated assets, compounded over time creates wealth.
