No Mentor

This is indeed a big obstacle on your way to success. You need a mentor to guide you toward your vocation.

Vocation it's inside you and sometimes it's well hidden, so it's hard to tell someone, "That's your vocation!" Vocation is subtle, it's like a song only you can hear.

At the entrance on the Delphi Temple is written, "Man, know yourself and you will know the Universe".
