Like Time said, there's different Masters. Some may fit your interest, others not so much. It's best if you're detail about what you want, there's likely a master-type for you.
It may take some time to find the right fit for you. When a Master answers you, look for one who is detailed himself, not one sentence replies made of faces and short cuts, in person one that does not stutter or use fillers (um, uh), who knows what he wants. Eliminate the ones that don't sound right for you, and learn about the ones you like.
