Zack: You should cut your hair and trim your beard before you interview for an internship.
Me: I would definitely do that.
(I am a law student with shaggy hair and a beard. I don’t look like a lawyer should look. I’m aware of this. I just don’t care right now. When will I ever get a chance to carelessly grow a beard or have longer hair again? The fact that “I don’t know” is a possible answer to that question is reason enough for me to do it now – not later – not never.)
