Two points.

First, I might recommend the Metaphysics before the Physics. Second, I think reading the original Aristotle as a novice and alone is perhaps not the best move. I think it is best to start with a commentary or something more pedagogically suitable. Contemporary expositors like Edward Feser or David Oderberg write lucidly and approachably on the subject (see “Scholastic Metaphysics” and “Real Essentialism”).

That never said, it takes time to understand this stuff, especially when all sorts of bad intellectual habits must be broken.

Asking from genuine curiosity: what sort of bad habits did you encounter when reading philosophy?

I can identify with this from analogy: I recently started learning a guitar solo that is probably a couple of steps above my current skill level, and it served to reveal some bad fingering habits I had that never became a problem until I started to push the limits of my playing ability.

I would recommend starting with Categories from Organon:
