Throughout my career, I had a lot of mentors, and I just adopted them. What I found is that, especially if you're young, when you go up to people and say, 'Would you mind being my mentor?,' their eyes widen. They literally step back. What they're thinking about is the commitment and time involved if they say yes. And time is something they don't have. So I would not ask them to be my mentor, but I would just start treating them like it. And that worked very well for me.
