But they don't use any advice on themselves because they don't believe in themselves. We can take advice from anyone, we have to do what we are good at and know we can do and slowly do what we can't. People don't look for it, they talk to people for their own benefit and ask them what to do and how to get profit and how to succeed in life. Your thinking is wrong. First of all, even if that mentor is successful, then if there is any mentor, then you should go for advice from him, from whom you will be called a fool.We should do something new by ourselves, by which we have seen something new in this world, and from that, a mentor should learn something from us and work. It is better to consult a mentor than to do nothing at all.
In the end, it all comes back to yourself, what you said is true, we can accept advice from anyone and of course people around us such as friends or family will give us encouragement or advice, but in the end it depends on us how we will respond to that advice. In addition, we must be able to convince ourselves with what we have mastered by continuing to develop it to be more mature.
We must strive to achieve success and consult with people who are more experienced or like mentors, that is one way that can be done, moreover, it is not illegal, besides I think successful people will not be stingy in sharing knowledge, including with mentors.
