One day when I left a bookstore and walked on the street, I saw a woman standing outside the post office. She looked pale and worried. I stopped and asked if she needed help. She told me that her foot was hurting and she had to go to the hospital fight away, but there was no taxi. I wanted to make a trip to a food store later that day. I asked the woman where she was going. She told me the name of a hospital which was actually on the way to the food store. So I said, My car is parked nearby, How about my giving you a ride? It will save you some time and money. She agreed gratefully. When we got to the hospital, she thanked me again and again. Then I went to the food store and picked up what I went for. As I was waiting at the checkout, the man behind me said that he had a coupon  for 20% off anything in the store. He gave it to me because he had an extra one and he wanted to do good things to others! I thanked him and let him go ahead  of me in line to check out. Each action creates a ripple   that finally comes back to us. Do you believe it? What does the author mainly want to tell us?
What goes around comes around. No man can do two things at once. Where there is a will there is a way. God helps those who help themselves.
