I never actually looked for a writing mentor (who wants to stay anonymous, because, as he explained to me, he doesn't like to be bothered by people and prefers to live a quiet life—so I shall call him Basil Bee, or Vasya Pchelkin in Russian). We somehow found each other (on Twitter, of all places) and over time fell into the roles of a student (me) and a teacher (Pchelkin), and then it kind of went developing from there (we meet once a month or so, occasionally text and exchange emails).

I think when you're ready for a mentor, you'll find one.
