I liked the article because I feel like I'm at the stage of my career that I need to be a mentor. But at the same time I don't feel like I know enough about everything.

I think there are a lot of people out there doing real work - who can benefit from a little push. that makes me feel that a) I have things I can teach and b) that its ok to not know everything - even what others may think is "basic" stuff.
