Agreed, not everybody needs mentor, you might never know if you're good than the individual you're going to meet for mentorship. Every mentor are like us and don't have any special talents. Trading relies on experience hence when you start gathering enough experience from your failures and that of others, you'll understand how to trade better and starts making a profits. Mentors charge alot for mentorship hence they aren't the best options financially. You have all the information you need available on the internet. What you have to know now is how to search for the information and you can get that without needing a mentor to help you with that. Mentorship isn't a bad idea for those upcoming traders that can afford it but for those that can't, you can still make it on your own.
As much as people think they don't need mentorship, I don't think it's a bad idea because there are people who can not learn on their own. This is enough reason why you will still need people to guide you, because nobody knows it all. Still, people are learning daily, and we are more knowledgeable than others. and true that mentors are not more special than us, but like I said, we just have to be better than one another, and that is the difference. There is nothing wrong with wanting to know more about trading, and if you take this community, for example, you will know that mentorship is actually, one way or the other, very important.
I think people are always underestimating the power of mentorship, and people are ready to learn, but they are not ready to actually allow people to help them. But is only when things become very bad that you will see people complaining about trading, but at the same time, fail to learn.
