Physically, it's in the eyes of the beholder, I've been told I'm good looking and I've also been told I'm ugly. Which really befuddled me for a bit.
I agree with your points especially grooming yourself. I feel better outside and within myself.
For me, what I would like to change is that women are perhaps honest to themselves with a guy they find attractive and communicate that to them. Guys don't receive compliments much, we get mostly criticism.
