the hardest thing is, I think, to actually get yourself together and start doing stuff.
On the topic of books:
idk 'bout others, but I find it rather pleasing when all the info i have comes together neatly (wanna be a fucking astrophysicist in the future), so I'd recommend reading stuff like Gleick's "Chaos: making a new science" and Freud's introduction to psychoanalysis. The latter is long, but it kind of helps you understand things.
I found this helpful, though it depends really on the worldview one has before learning about magick. I prefer reasonable explanations and systematized knowledge as grounds for belief.
