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.
Having a mentor is not a bad thing, the necessity of it is just to get a good guidance in what ever you decide to pursue (career or whatever), most of the time and for some people too, mentors can be a source of hope for them in which they draw their zeal from and become motivated. Some people actually needs to pushed before they can stomp into action and that's the purpose that mentors serve for some persons.
