I think that it’s important to know the truth about trading whether the information is good or bad. It prepares us for uncertainties. Yet, I think also that it’s not helpful to focus on, ". . . how tough trading is, and how very few people make it". This may affect your psychology to perform well. It’s hard, but how did others manage? It’s doable***. So, you must make a habit of learning from the very best. I think that you need to invest some money to pay a skilled mentor or school to learn. Besides, you must spend a lot of time practising trading until you know better. Furthermore, you must read, research, and watch videos. I have been reading material here at Babypips.com and also at Investopedia, etc. They have a lot of valuable information.
