It can help to learn something from others, however, the main teacher of a trader is the market itself and his own experiences of it.
Sure, sources can provide different theories and info, but in the end, you utilize it in your own way.
No doubt that the market is your best teacher, but you can say that this is a teacher with no emotions who doesn't care about their students haha theoretically, so make sure to find multiple mentors and sources of information that you can use this teacher to test your strategies.
In trading, you can copy someone's style but you cant copy his/her mindset and perspective and this is what matters in order to survive and be a shining star in this market. All you need is to train your subconscious mind with strict discipline.
