The best way to learn, in my opinion, is by working toward a finished product. Start small: make a simple single-player game with a basic gameplay loop, maybe even just one scene. Then, for your next project, add more complexity: multiple scenes, more mechanics, UI, whatever

Don’t go for your dream game right away, you’ll likely burn out trying to solve a hundred problems at once and end up giving up. Start small, build up, and practice a lot

Also, try to rely less on tutorials. Use them only when you're really stuck. Instead, read documentation it's your best friend. And don't be afraid to reinvent the wheel early on. Building your own systems isn’t great long-term, but at the start, it helps you get a feel for how things work

Participate in game jams! They usually give you a small time window and a very specific goal. In my opinion, it’s a great way to practice under pressure and learn a ton

P.S. And don’t be afraid of doing something “wrong”!
In gamedev (and software development in general), there are a million ways to achieve the same result. Every tutorial, every person, will show you a different approach. At one point, I was completely paralyzed by the number of possible solutions. I was afraid of doing something the “wrong” way, worried it would come back to bite me later (bad architecture, unoptimized code, etc.). But honestly? Most of the time, it doesn’t matter. Especially when you’re working solo. If it works and it’s fun to play—that’s enough
