While I know it is not the answer you are looking for, I would say you can't – they find you. This is just my experience. I put a lot of stock in the importance of having a "mentor" early in my career. And I lamented the lack of being able to find one. I eventually changed gears – different job in a different field – and found someone I consider to be a mentor. The most interesting part is that instead of this person being someone I want to be exactly like or even someone that I share a great deal in common with, I just find myself trying to do what I think they would do in situations I am faced with. It's the way they handle themselves, communicate with others, make decisions, etc. So I would just say be involved in as many things as possible and be open-minded. Ideally you will share a lot in common and be in the same field. But I don't think that has to be the case.
