Ask HN: When should you look for a mentor?
I'm trying to find a mentor for my side project, which isn't yet a startup: it's an idea and some code.<p>I want to approach a professor I had in undergrad to be my mentor, but I'm not sure if I have enough to approach him yet and generate interest in helping me develop. He's the foremost expert in the area of my side-project, and he's very in demand/probably doesn't have much time.<p>At what stage should one approach mentors? Idea/Basic Implementation/MVP/Product Release?
