> 2. Read the management discussion in the 10k of a public version of the company you work

YES! Management's Discussion of Risks section of 10ks is amazing, and really easy to read.

I think it's nuts to work at a public company and NOT follow your employer's 10ks and earnings calls (at least on and off, or at least when newly hired as well as for context any time there's Big Corporate News)

It really helps cut through management's BS when you can just read how they're describing the situation to the shareholders rather than the spin for internal audiences. It's the One Secret Trick that will give you an idea of what the motivations and interests of your company's leaders are, as opposed to what they claim or you guess that they are, which then ends up being super useful for say, judging which project has a better likelihood of becoming important, how to sell things internally, etc

Nice, we are going macro now. This is often overlooked, if you did a lateral industry shift, you have to get conversant in the industry lingo asap, so don't forget the jargon and concepts. Most standard industries are well documented, even though the documentation may be less than stellar (I'm personally looking for IP industry material to binge on, nevertheless, because it's IP(intellectual property), they don't publish much training/guide material). I tend to do the book thing but on subreddits of the particular sector/industry, I think that browsing topics on reddit is the fastest way to get conversant and begin to absorb knowledge, or more specific, awareness of existence of knowledge.
