I was into asm back when Amiga was around and lost the will and knowledge over time (mostly since programming is more of a hobby now, over the last couple of years). But, I had a strong desire to get into asm again and I did it a bit unconventionally. It worked, though. Get a TIS-100 game and play it (that got me interested again). After that, I compiled simple(r) C programs with gcc and looked at their .S output. After that (along with that) grab a tool like ollydbg, x64dbg or (if you can!) IDA Pro and open up your favorite programs and modify them. Whenever you stumble upon an unknown (to you) instruction, look it up in the intel manual and google for it to see idioms people use. This process has worked really well for me, for now, albeit it feels like I'm cracking software or something like it (it's fun though). Along with that you can start writing asm blocks in your programming language of choice and/or full asm with any of the assemblers (flat, yasm, nasm, whatever). Only thing you need to know beforehand are the basics of C and data/memory manipulation.
