Well, its definitely changed me for the better. I realised that there is a LOT more to life than just looking pretty all day long - so I've stopped wearing makeup now. Also, I'm a lot less materialistic, I don't see the point in buying useless stuff for no reason.
I think in essence, its made me more of a simple person. Half of the stuff I used to do and what I felt was a necessity isn't of any value to me now.
