No way. Never. Even though I have a big nose (which you don't see clearly in my pic - it only becomes obvious if I face side-on), I figure if someone has a problem with that, it's their problem, not mine. (Besides, I don't have to look at my own nose all day...!) I feel comfortable with how I look in general, even though I'm not gorgeous by societal standards. Or to put it another way, I feel like I look 'good enough' by my own standards (my standards are that if people don't run away from me screaming, then I look OK!). So, no need for plastic surgery. On the other hand, if I was disfigured in a car wreck or something, then I would be keen to get reconstructive surgery. But not just to 'look better' in general.
Ultimately, I expect people to like me for my personality not for how I look. If they disregard me based off of non-optimal looks, then they're probably not the type of person I'd want to hang out with anyway. So with that attitude I would just not be a good candidate for plastic surgery! I just don't care enough about it! So in conclusion, I wouldn't have plastic surgery even if I were actually paid to do it. Intriguing question though!
