I feel like there are more and more people who only THINK they can program, but in reality they barely can make the “Hello, world” program. Many of them come from all of these “online courses”, I’m not saying that from there come only the bad ones, but many of them are bad programmers, who just think that one or two courses is good enough.
You have to gain experience by doing actual work, not by doing pre-baked exercises. In real life most of things you have to solve with your imagination - Stackoverflow will only provide you some raw draw!
