A lot of guys refer to being in the decider role as "flipping the script" on a girl. By this, they mean to turn it into a tactic. They realize that girls have egos as well and once disturbed can cause them to chase endlessly and give no heed to the actual value of that which they're chasing.
For a man, though, it's the tight rope act of the century. One false step of you pursuing her and the magic illusion is broken. So, instead of flipping the script on a girl, I'm simply advocating rejecting girls as healthy exercise of your self worth and self esteem.
You Only Involve with YOUR Best
You have a finite amount of time to talk to girls, date them, sleep them, let alone make one your girlfriend. As such, you shouldn't be so quick to take what comes easy. God forbid you knab a really "rare" one, you abandon all rejecting power and consider yourself lucky until such a time as something better presents itself.
Yet, by being selective you seldom if ever talk to a girl that doesn't feel rare and checking all the tick marks in your attraction bar both short term and long term. Your whole "pool" as it were is filled with girls that you have a lot of common with and that are very pretty.
It Helps You Realize You Have Value
When you reject a girl for not being what you want, it makes you realize that not every girl is good enough for you. This isn't a mark against her, but rather, again, what you find attractive. You start to believe that a girl you bother talking to must be valuable by the fact that you chose her out of other girls--and, by this logic, you are a source of giving value rather taking it.
It isn't about hurting their feelings that gives you a boost, but rather hurting their feelings is the sacrifice you have to make in order to get what you want. As males, we know all too well the pain of rejection, and I honestly believe a lot of "douchey" behavior like not texting the girl back and even cheating is a misconstrued desire to protect the girl from a face to face rejection.
What men don't realize, though, is that rejection is a necessary part of acceptance. It gives context to accepting a girl and falling in love. If you love everyone then there is no crossing eyes with a stranger from across the room and immediately falling for them. That only is important if it doesn't happen all the time.
You Secretly Want It
What's maybe more important than being with dream girls is being the type of guy that is with dream girls. That guy is different from you because he won't be interested in something in front of him just because its in front of him. Like someone who's dined across the world, he knows a fine cuisine when he sees it. He has taste. You want to have be a decider, not a bottom feeder.
Go out there and reject some ladies, Gentlemen.
