A mentor is someone who is a more experienced individual who helps you not make dumb mistakes, or mistakes that you don't have to make.
A good mentor can tell you what you should be obsessed about and wether you should be obsessed about it at all. 'Cause if you're young you tend to obsess about the wrong things.
You should have many mentors, all of them for a different quality. Why? Because you should learn things from the people you admire, and you probably admire more than one person.
Go find your mentors. Learn. Enjoy. Be yourself.
