"Instead of looking for a mentor, just find somebody who can answer some questions you have. Then, if you think they can answer some more, ask them again. In reality, a mentor is mostly just somebody that answers questions more than once. That’s it. It’s not cinematic." -- Love it. Perfect framing. It's okay to call that person your mentor, if the two of you think it's the right way to define the relationship. Don't let the lack of an official mentor hold you back from asking people some questions, and then again.
