[WT Sharpe]

.....You may never have proof of your importance, but you are more important than you think. There are always those who couldn’t do without you. The rub is that you don’t always know who. I recall an old Sufi story of a good man who was granted one wish by God. The man said he would like to go about doing good without knowing about it. God granted his wish. And then God decided that it was such a good idea, he would grant that wish to all human beings. And so it has been to this day.
