One day, a man found the cocoon (茧) of a butterfly and he brought it home.
A few days later, the man saw a small hole in the cocoon. He sat and watched for several hours as a butterfly struggled to force its body through that little hole. Then it stopped.
So the man decided to help the butterfly. He took a knife and cut a bigger hole in the cocoon. The butterfly came out of the cocoon but it had a weak body and small, thin wings. The butterfly didn’t start to fly.
In fact, the butterfly spent the rest of its life crawling(爬行) around with a weak body and thin wings. It was never able to fly.
The man acted with kindness but he didn’t understand that he had done something wrong. When a butterfly crawls out of the cocoon, it must struggle. The hard work of getting out of the cocoon forces the fluid(液体) from the butterfly’s body into wings. It helps the butterfly be ready to fly. If the butterfly never has to force itself out of the cocoon, its wings never get the fluid and it can never fly.
Sometimes struggles are exactly what we need in our lives. If we lived our lives without any problems, we would never learn or grow. We would not be as strong as we could have been and we would never fly.
So, the next time you are faced with a challenge or a problem, remember the butterfly.
Struggle a little – then fly!

Here's an interview to a pilot about his life.
(R="Reporter;" P= Pilot)
R: How much time do pilots actually spend flying a plane?
P: It varies (WES'J) from about 20 minutes on some domestic (区别) flights to as much as 18 hours on international flights. It all depends on if the flight is a short- or long-haul flight.
R: Do pilots take breaks during flights or do they fly the whole time?
P: Yes, we take breaks during long-haul flights. Airlines assign (指派) three or four pilots to long flights. We take turns flying the plane.
R: If pilots are traveling all the time, how do they deal with jet lag (时差)?
P: Jet lag is annoying for almost all pilots. I try to go to sleep as I would at home.
R: How important is it to know the weight and size of the plane you are flying?
P: It is very important. We weigh almost everything put into the airplane and make estimates (估计) according to the number of people on each flight.
R: Do pilots eat the airplane food?
P: Yes, we eat business class food! Airplane food changes every season and is very delicious if you don't hate eating lobster (龙虾) every day! The pilots on the same plane are supposed to make different meal choices so that if one of the dishes causes food poisoning, only one of them will be sick. That way, at least one pilot will always be well enough to fly the plane!
