Everyone is not blessed with this joy because to give, you should expirience the feeling of not having.
Many a time the expirience of not having is thrust on you to show the "aukat"of not having by people of inheritance.
People sans inheritance mind their business and help with whatever is available.
If you feel happy to give don't rob Harry to pay Tom .Instead see that your cup overflows with your mehnat and then distribute.
That is giving,that is expiriencing the joy of giving.
It is not about how much you give or how little you give.It is about how much you are ready to part with from the fruits of your hard earned labour.That determines the quality of your joy.
