Thomas Edison tried two thousand different materials in search of a filament for the light bulb. When none worked satisfactorily, his assistant complained, “All our work is in vain. We have learned nothing.”
Edison replied very confidently, “Oh, we have come a long way and we have learned a lot. We know that there are two thousand elements which we cannot use to make a good light bulb.”

The job of a pilot is difficult and risky, but prestigious. Airline pilots often travel thousands of kilometers and can find themselves in a different time and climate zones every day. see all parts of the world and get to know new people almost all the time. But a pilot also faces problems. often suffer from jet lag and can become tired when flying through different time zones. spend many days away from home and families.
Although many people think it is a real dream job, pilots must be responsible people, because they have the lives of up to a few hundred passengers in their hands. They have to have hundreds of hours of training before they can do their job. Pilots must remain calm in dangerous situations and always have to make the right decisions. They need to see and hear perfectly. About 60 % of all pilots fly commercial airplanes, the rest fly cargo and private planes, as well as air force planes.
On average pilots spend about 70 to 100 hours a month in the air.

Until the 1960's, team sports were not played on a global scale. In Europe, people European games, and in North America we played American games. The only real "global" sports individual sports, such as golf and tennis.
At that time, rich Americans could travel to Europe on holiday, and play these two games; but whole teams of sportsmen did not often travel around the world, it was too complicated and slow!
The first worldwide sports competition was the Olympic Games; but originally the Olympics were only concerned with athletics; they did not include the wide variety of sports that they now cover.
So as far as team sports are concerned, America has grown up with its own tradition; we love our “football” and our baseball and our basketball. We don't mind if these sports are not popular in other countries. That way, we can organise the “World Series” baseball championship, knowing that a US team will almost always win.
