There is a reason it takes time to learn anything useful

There is no impactful and differentiated skill that you can learn very quickly. If it was possible, then most people would have acquired it. If many people had that skill, it wouldn’t be differentiated anymore. It’s because of the long learning period and the time it takes before you start seeing any meaningful progress, that most people give up. As a result few people acquire it and it becomes a unique differentiated skill. It’s as simple as that.

So beware of anyone who promises to teach you something magical in a short period.

And if something that you are learning is showing slow progress ( there has to be progress though ) then it might be a good thing. Double down on it and don’t give up. You will have a superpower at the end of it.
