Mentors can be a tricky thing. It can make us feel so reassured that somebody wants to take us under their wing.
Who, me? You want to mentor me?
Then we get to boast that so-and-so is our mentor. He/she chose ME. The tricky part is that it can be easy to become emotionally dependent on what they think of you and your work. Mentors, after all, are human. Just as we get validation from training under them, they can get validation in knowing that we feed on their approval and encouragement.
In the end, mentors are people with expertise that teach us a craft/skill/art that we want to learn and someday master. And we should have a multitude of them. It’s best not to put all our eggs in one mentor basket. Those we learn from and those we lean on are not the same people.
