1. You are trying to learn a lot of different things at once. I don’t think you’ll find many “coding” experts in the real world, but you will find react experts and flask experts. I think you need to focus on something to get the satisfaction you’re craving. You still might not have found your favorite language/framework/project, so it’s fine to keep searching as well, but I would avoid going around in a circle spending a week barely scratching the surface of the same 5 skills in a cycle.
2. You will never stop learning. You will get better, but there will always be something new to learn. Even if 90% of your code works “intentionally” as you say, there will still be 10% that you need to trial and error and stack overflow.
