This. Practically anyone claiming to be a mentor or wanting to be a mentor has issues. It's selfish ego boosting stuff. Additionally, in almost every discipline the world changes so much and the real decisions are so context dependent that any "mentor like" advice is as likely wrong as right. And if it's simpler stuff then it's just a random tidbit of advice from one person to another, or it's in a book somewhere and a random comment "dude i read awesome book x about y the other day" works - the person either doesn't care and won't read it or they do and they will.
