Options in Life

I have been pondering over a question in my mind this few days.
" Why am I not giving away half of what I have to save the people in Africa?"
" Why I could donate all the money after they die, but not when I am alive?"

Is it because of my selfishness is greater than my compassion? or this is simply the reliaty ... no one will do it.

Whatever it is, I cant get a firm answer. But I am close to a conclusion :

"I still got so many options in life now, this Options + the insecurity feeling blinded my purpose in Life."
