Don't put all your trust in a mentor on achieving your goals in life, it is because your mentor and you had different situation that has also a different solution, so i think we need to have faith in our own self capacity to pursue our dreams not just trusting our future to others or to mentors hand.
I won't disagree with what you've said about believing in ourselves. But as a person, you have a way to discern whether the mentor is really there to help you and show the best out of yourself. And if not, you know when to run away from that type of mentor. It's rare to see mentors that are there to help you with what you're starting. Most mentors are there to milk money from you as their mentee and all they want is the subscription that you'll pay them. That's not a legit mentor but the realest ones are wanting to see the best of your shape and results driven.
