I was thinking like you, but not anymore.
When I started to learn, I learned everything on my own. In hindsight I realized that I was lucky. Although lucky is not really correct. What I mean is that from start I started with the right approach to become successful. Starting with the right approach was my "luck". I could have started with a wrong approach too.
But in the past years I saw a few friends try to do the same. They failed, and when they told me how they started I saw essential errors in their approach that were (might have been, as you are never sure) responsible for the failure. Following a initiation course might have shown then, the right track to start.
So I think following a course can help you at start, but they will never teach you a system to become a millionaire. That work you will have to do on your own.
If you want to become a good carpenter but hold your hammer upside down from start, you will get in problems. The same applies for traders with the only difference that for a trader that starts it is very difficult to know if the road he is following is the correct one. He can study for years to find out he was wrong from start, or he can find out that it was the good way but hard to solve the encoutered problems.
So if a trader encouters a problem it can mean two things:
- he should solve this problem, but he is on the right track
- he should start from scratch again as it was a dead end
But how can he know what the exact problem is? There an initiating course might help, but that is even not sure, as in trading there are no certainties.
