Mentor is good to guilde one at the beginning of trading but you dont need a mentor throughout your trading journey.
Those traders that are not confident with their own skills feel that they need one until the end. But soon, they will get to learn that they don't really need one of them. It's because what they need is to learn more of themselves and the strategies that they have learned through their trading experience. It's better to rely on themselves than to rely on someone, on a mentor that they think is good enough but they can be better than that. And then, the money that they'll pay for that guy, it should be enough when they have started and they have to cut ties with that although they shouldn't burn bridges.
When a trader does not have confidence in the abilities they have mastered, of course it makes them less precise in deciding something and they could still fail because they hesitate in deciding when trading and for those who continue to focus on learning strategies and continue to practice trading, one day they will be able to achieve success in trading.
If we choose not to rely on a mentor then we must continue to try on our own and we will also always be satisfied with the results we get when trying to trade and when we still experience failure, we continue to try to find out the mistakes and fix them, but if we choose to learn from a mentor and experience failure, of course this will be very disappointing.
