Hi! I'm writing this blog because I have no idea what field I want to study/work in, so I decided to ask You for some learning/practicing material so I can touch the surface of these fields(networking, AI, etc). I have already tried this website(https://roadmap.sh/) but I couldn't follow along mainly because there was no exercises(and I didn't know how much knowledge in each category-like POSIX- I needed).

Can you give me some advices(other than watching a 10 hour YouTube tutorial about it :) )?

Thanks!
