most mistakes of traders are;
* Thinking it's a get rich quick scheme or thinking that it's easy.
* Having no proper training in the craft to attain knowledge about it.
* Watching one two or three video's on YouTube by one YouTube influencer and think they are ready for it or thinking they have known the craft.
* Having no experience traders that is good in the craft to guide them.
I completely agree. Trading is not a quick way to get rich and it is much harder than most people think. To be successful you need knowledge, emotional control and good risk management.
Emotional control and risk management are the most important things that you must learn if you want to be a successful trader...when it comes to emotions we are referring to psychology, the most crucial part of trading...This deals with how well you handle losses and how you deal with the thought of not hitting your target..and lastly, knowledge too is important just as you mentioned, without acquiring knowledge you are just a gambler not a trader
