It is better to learn directly from an experienced person. It will take less time.
Having a mentor for guiding you in trading if not that easier one because people who are experts in trading must be having lots of scheduled works rather than guiding you for free of cost or even for a fee. I agree if you are having a mentor then it will save a lot of your time but definitely it will cost a lot at the same time which is the reason why most people are not going for it.
I believe there is also a question mark about how mentors could be making money by trading anyway, so why would they charge someone for teaching them something?
I understand that they are spending their time and that is why they are charging money for mentoring but if they are so good at trading shouldn't they use that time to trade instead of teaching me? Would be a great way to make a profit if they are so good at it enough to be a mentor. This dilemma means that you either have no mentors because they are all trading, or you have mentors that you do not trust the abilities, and that is why it becomes a challenge to find a mentor that you actually trust.
I personally do not use any mentors at all, I try to do as great as I possibly can without the help of anyone else, sure I read and watch but not because I think they are mentors but because I know what I am looking for and what I want to learn.
