But and it's pretty common sense when you want something from someone in
essence you're relinquishing power to someone because they could say
no.
You don't have to relinquish power to get something from someone. There are a multitude of things you can do to get it from them. It all comes down to various tactics of manipulation. Whether you can convince them that it's worthless, or that they'd feel better if they gave it to you, or that you could offer them something of apparently higher value in return... or you can use some form of leverage to force them to give it to you... The possibilities are endless. The game doesn't end with simply asking them...
In general what works best for me is to play the charm card, it's hard
to explain but basically you have to appear to be smiling and be
easy-going, almost carefree in your demeanor.
That may work on some people, but for someone like me, I find "charm" to be fake and disrespectful and I often scorn and redicule it. If you wanted something from me, you'd do better to show your strength and value than your submission and asskissery. Which again is why its relative to the personality of your target audiance. As I said before, there is no one size fits all.
Masterful Manipulation requires the ability to stay cool under pressure, flexibility, and quick wit.
