Nice... Everyone has things to purse and in this world & most of these things can be very complex beyond our imagination. Many people are so concerned about the outside to the extent that they overlook the interior part of the whole ordeal.
Trust me, any man that loses focus about himself will find it hard to focus on other things because, like you already know, you can't give what you don't have.
I think it's high time for us to realise that thinking me doesn't be used as a yardstick to call someone selfish. It's only a healthy person that will be able to breathing life to his environment.
Nice one
