Talk me out of getting a rhinoplasty

Been to a plastic surgeon consultation. I am white with white person nose (british), my nose isn't that big, but it is slightly asymmetric ans its always bugged me (im in social media so i always look at photos of myself). Surgeon says he could correct this asymmetry but it would be best done by making the nose a little less projected (smaller). Why should I not do it? He makes it sound very easy and simple.
