A simple metaphor to explain something a lot of people overlook.
I have 100 biscuits (cookies to some)
You have 2 biscuits
I convince you to give one of your biscuits to some one who has no biscuits.
You now have 1 biscuit, the other person has 1 biscuit.
I still have 100 biscuits.
Congratulations... you now know how celebrity charity drives work.
Now.. what would you do if you won millions on the lottery?
(I choose options 2 & 3)
