One thing is learning and another is following guidelines, just as when you get a product you read through the guidelines on how to make use of that product, but so many investors always neglect that and go straight to taking every decisions that comes to their mind. Most times i follow guidelines but in rare cases I follow my instincts looking at how the markets goes and it sure turn out well but it's best to stick to mentorship and advice.
Yes, having a mentor will of course speed us up in gaining insight or knowledge quickly, but this does not mean that what they teach is accurate or successful in various ways in every market situation. Therefore, it is important for us not only to rely on guides or mentors, but also for us to continue to learn independently or combine every indicator that has been taught before. Yes, of course every trader has a different style, some are successful and not necessarily suitable for us, and it is much better for us to determine our own trading style than to follow other people.
You are right that we should continue to learn ourselves, and not be stuck with what mentors say, but it is still important thy at newbies shouldn't make their own moves without mentors approval too. Obviously if the mentor is a shitty one that means it is not going to be easy at all, but that doesn't mean that we are going to end up with anything that will take a long time, we can't really end up with much issues if we deal with any of this, we just need to focus on how to make a better price in the end.
Many people focus on trying to make their move, but if you are brand new in the market then you can't really make much moves, it is not going to be that big and we can't really get away with that much of a profit.
