Once, I got lost on a trip. Then I met an old lady and asked me the way.
The lady told me, "Turn left from here until a school, and then turn right from there. Go straight on and you find a place with a crossing..." With that, the old lady thinks for a while and then she said," When you get there, you are not far away from the place which you live. At that time you'd better to ask someone else. Even though I tell you now, you may not remember."
According to the old lady's help, I got to a crossing soon. Then I asked a passer-by there and quick turned back to my living place at no time.
Although it was a minor matter, it influenced me greatly. Now I realize our abilities are limit and many of our problems can't be solved overnight. So we must act step by step, gradually approach the destination.
