When it comes to generosity, it's important to remember that quality trumps quantity. And, often the gesture means more when it's unannounced. After all, how generous is it really, if you're expecting credit for it?
To get what you want, give it away. Have a generous spirit, and show yourself how abundant you are, even if you have to start out small. It's that generous spirit that will bring you all the abundance you could want.
