Unrelated: How does one find a mentor/mentoring group? I've been thinking about it a lot lately, how for the first time in my career I'm without someone I would call a "mentor" and how that's probably not great for personal growth. It seems artificial to look for someone to call a mentor, as opposed to happening upon a person that you look up to and makes you feel inspired to grow. Can you shed some info on how a mentoring group works?
