2) Consider those in your extended network

If your friends and relatives have already given you enough unsolicited advice, and you don't think that's the path for you, your remaining possibilities are those who don't know you as well or don't know you at all. 

How can you ask a complete stranger for such a large commitment? The first step is to contact people in your network. 

A kind word from a common friend might go a long way toward kicking off a mentoring relationship.
