When I was just starting to produce, I would just get my hands dirty in Ableton and mess around, while watching YouTube tutorials all day. This was about 4 years ago...and that went great, but the only problem - for me personally - was that I got too comfortable with this method of learning alone, and with how much I had learned. I just kinda coasted down that path for a good long while, but realized I could've been working harder and making more progress, so earlier last year I basically decided to start teaching myself all over again and this time I decided to read (mainly because I have 2 jobs with a lot of downtime and limited wifi at both haha). It definitely helped to build on knowledge, and get some creative juices flowing. I also started watching YouTube tutorials again over a wider range of topics (not just massive patches l0l) and even took some notes haha. I think it helps to mix things up.
Here's what I read:

An alright selectionn...
Ableton's music strategy book was perfect.

..."Last Night a DJ Saved My Life" was kind of hard to swallow, but it was $0.04 on Amazon and gave me something to do at work, so I figured what the hell and gave it a read haha. I actually learned a lot about the history of the genres that I didn't know though. I liked that. Definitely made me appreciate the art a little more too.
I also read Daniel J. Levitin's "This Is Your Brain On Music" and highly recommend it!
