Sasha Dichter has a practice in which he will make a commitment for a period of say four weeks to respond positively to everyone who asks him for money. Whether it's someone on the street or a charity, doesn't matter he gives them something. It may not be a lot, but he says yes. Over time the effect on his psyche and soul is that he begins to see himself as a generous person, a philanthropist.
How would this experiment impact you? What would you discover about yourself? How would it change your views of generosity and self?
You'll never know unless you try it.
