I think working with it in practice is the only way forward. Looking up info, build something, work more, and let it become a feedback loop. People work long with systems before they "get" them.

Programming is not a "school" activity for me. It's a craft, you do stuff. That has eventually led to a depth of knowledge in various topics inside programming.

(Digression: With that said - we should think of a lot more "school" stuff as skills and crafts - stuff that you don't read to understand but you get better at with practice. A lot of maths class is skills, not knowledge.)
