I came across these rather powerful thoughts:
If you find yourself stuck in traffic. Don't despair. There are people in this world for whom driving is an unheard of privilege.
Should you have a bad day at work, think of the man who has been out of work for years.
Should you grieve the passing of another week-end, think of the woman in dire straits, who works 12 hours a day, 7 days a week to feed her children.
Should your car break down and you have to walk to find assistance, think of the physically challenged person who would love to take that walk.
And last of all: I cried because I had no shoes till I met a man who had no feet.
