For learning programming I always recommend that you have a specific project in mind, so instead of following a book, you follow your project's needs and use books as a reference.

I learned (intel x86)assembly from joining a cracking group when I was adolescent, it was my first programming language. Nothing beats being taught by masters of the craft and competing and contributing as a team.

Today I teach kids ARM assembly using microcontrollers like arduino unos or nanos and controlling a motor or servo, then I add more and more complexity like explaining klipper architecture, so they learn c and python.

With kids, the social part is very important, and making real things that move and react on the real world too. I suspect is of great help for adults too.

It is probably too dull to learn assembler today, on your own (alone) on a powerful computer. With a microcontroller you have a machine that is so constrained in resources that you really need to use c or assembly.

HN has very good resources about assembly, you can search them on google "hacker news assembly" or "hacker news reverse engineer", use zotero to aggregate the links.
