"Just Be Nice."
Oh, really? You don't have to be nice to anyone. You can be a complete jerk and still be attractive to others because people respond to emotions. Being nice triggers no emotional response, except maybe boredom. If you make people feel anything, even anger, they will find you more appealing than if you make them feel nothing at all. People aren't attracted to niceness (they only tolerate it); they're attracted to having to earn someone's respect and approval. Become that kind of person, and save the "niceness" for dealing with dumb animals.
"Just Be Yourself."
Everybody is capable of being vain, stupid, cruel, and self-centered. Yes, really. So to most people, "Just Be Yourself" means saying whatever comes to mind, being rigid in beliefs and opinions, and dressing like a slob; it means being rude, arrogant and negative; it means being whom "everybody" believe you to be. This is all bushlit. The best way I've found to deal with people is to be the kind of person that generates respect, admiration and trust -- no, not my on-line persona, but a real-life combination of Mr. Spock, Obi-Wan Kenobi, and Danny Thomas. Yes, it's an act, and I'm not being true to myself, but there are sacrifices that simply must be made to get ahead in the world, and putting on an act is one of them. Sickening, but true.
