I'd say the most important things to take away from other top comments here are the classic book recommendations, but other than that I'd argue any online sources should be secondary to watching people use systems for a few months based on training that's written or goven by someone else. I'm a frontend person, started in graphic design, and I've never actually been very good at design, but now I'm doing straight up IT work in an office with visibly stressed people using computer systems I did the hardware setup for, but not the software. These are all basic Windows laptops with pre installed images and cumbersome auth flows. Being in this job has offered me more insight than any article I've ever read, so therefore I think it's better to have some observation or hallway testing experience before looking to refine that with any specific UI recommendations or UX strategies that are rooted in theory. That's why I love the classic Don Norman book, because it's rooted in watching people use everyday objects that have been designed at a remove from their real world context. Just watch people use your shitty startup webapp UI or corporate hellscape portal, under stress for half an hour
