Should I change my profile picture on Facebook?

[Lucas]

Well I was thinking on changing my profile picture on Facebook and I found one in which I looked really nice but problem is, in real life, I don't look so nice haha. In this picture I look really skinny and I'm not skinny at all, I was kind of fat before and I'm a little more thin now but not 'skinny' yet. Also, I've got some pimples on my face which aren't noticeable on that picture. I don't know, I just feel like people will look at it and think 'wow, this guy has become more attractive' or something similar and then when they look at me in real life they'll be like 'no, he still looks the same'. I'm not 'ugly' though, i'm average-looking but that picture just makes me look more than what I really am. Hope you guys can help
