In a world with 7 Billion people I think it would be impossible for everyone to feel or agree on what is beautiful, what is sexy, or what is funny for that matter. Our senses and perceptions are indvidualized. This explains the old saying: "One man's trash is another man's treasure."
No one is capable of charming everyone, closing every sale, or seducing every man/woman. Like it or not rejection is here to stay!
I suppose when you think about it (risk) or the possibility of losing is what makes winning feel so goood whether it be in business or in relationships! :-)
