Educated, beautiful and well-off people generally refrain from bragging about such things, and when they do, it's seen as just as unattractive as when anybody else brags.
If people are being nasty to you, then ignore them. Don't ever return rudeness with rudeness or expect admiration from anyone without due cause. I guess, in general, the best way to get more respect, is to buff up one's etiquette, courtesy and kindness and weed out the people in your life that are giving you crap. Best of luck, I recommend starting with some Miss Manners columns if you need any advice on how to handle your behavior or the behavior of others.
