First of all, people will respond to whatever your point of focus is. If you think you are beautiful then people looking at you will "feel" you "radiating" beauty, they will pick up on that frequency and endorse how you feel about yourself. I started understanding this as I watched the popular reality show "America's Top Models". My daughter was an avid follower of the show in her teens and I had no choice but to catch some of it from time to time. It never ceased to amaze me how totally ordinary girls got on the show and actually won. I knew so many girls who far surpassed the ones on the show in terms of their natural beauty. These girls totally believed that they were beautiful and hot, and the strength of their beliefs got them on the show and took some of them to the finish line.
What ever you think are your best features, those will be the ones that people will notice. Whatever you think are your worst features, people will notice these as well. Whatever you focus on expands.
Secondly, people respond more to how we are vibrating towards them. So a very ugly girls who shines all her love on a hunk of a guy makes him feel good, and therefore attracts him. Makes sense doesn't it? Now she is focusing on his positive points, and as she does so he starts noticing all the nice things about her... it's all in the power of focus.
The bottom line is: if you want someone or people at large to change the way they look at you, you gotta change the way you look at you!
