I kind of went the other way around I guess. I never thought I needed to learn about money management, and only when I decided to jump into forex trading cause it was trending, I realized how important it is to know how to manage your money if you wanna trade or invest. What really helped were all the tips and discussions I found on
https://brokersinsider.net/ which is basically made for forex traders. While learning forex, I also started to understand how to handle money in everyday life. Really valuable stuff honestly.
