What works for some people doesn't necessarily work for others. There is no one size fits all way of attracting people. A lot of it also depends on your personality. You could get rejected for being tall, short, mean, nice, shy, annoying, the list goes on. It all depends on who you are and what the other person is looking for or attracted to. Trying to be something you're not usually backfires unless you fake it well.
