Personal experience, so here it is...
1. People will take you seriously.
Ever get the run-around when dealing with people? Well, when you know what you want and deliver it in a clear fashion- WATCH OUT everyone! When speaking with managers, customer service agents, when being direct and not backing down, it works wonders on how you get treated.
2. You get what you want.
Enough of being naive and letting people walk all over you. If you want something, you're going to get it. The guy you're dating is giving you the run-around? No worries, the b**ch will take care of this. Either you're in or you're out. Easy. He can be replaced. Simple.
3. When you feel powerful, you are.
Ever put on a pair of sexy heels and feel like you're on top of the world? Yep! Being dominant and feeling confident will really put a pep in your step. People can feel the energy that you project. Ever hear the saying "if you feel it, you'll be it?"
4. You get things done!
Allowing people to monopolize your time, or allowing others to take control has a way of taking you off track for things you need to do in your life. Well, have no fear- the b**ch is here. When you're on a missionm you know when to say "no" and others will respect you for it.
5. Intimidation can be a good thing.
If you're an open book and everyone knows your kind, this can lead to others seeing you as weak. If there is a sense of mystery, and an attitude at the right times- people will know to deal with you in a professional manner.
