I have tried tea tree before, and it's worked wonders on my dry scalp, but when I've tried to use it pure for acne the smell literally made me sick, so I've never used it for acne consistently enough to know if it'd work for me.

As per the not making sense thing, though. I get that. I wish college were a time where you could just do whatever the hell you wanted for like six years and then get a general degree followed by a job in whatever thing you enjoyed doing most in college. I love psych, English, music, art, even dance (which is the only one I've not done). I wish I could do it all.
