Startupschool lectures are really what you're looking for [0]. Paul Graham's essays are worth the time too [1]: He's written many classics in a well structured persuasive style. Sam Altman's Startup Playbook [2] is super nice as is Marc Andreseen's Startup Guide [3]. Some VCs like A16Z [4] and FirstRound Capital [5] post great content. Stripe [6], Indiehackers [7], and Patrick McKenzie [8] are other sources that are quite not as focused on startups but worth a look nonetheless.
Twitter is a gold mine where you'd find relevant content, but you'd have to literally mine it out.
I'd say though you could drain yourself going through all of this, but the fact remains that every company is different and what works for someone might not work for you. Also, there's lot of contradictory advice you need to sift through, a lot of obvious advice you need to internalize, a lot of advice you should simply ignore, and a lot of counter-intuitive advice you need to accept [9].
