It's a big difference between concentrating in the problem and concentrating in the resolution for it, for example:
Example #1:
Once NASA started to prepare the tours to the space, the had a big problem, which was, the astronauts wouldn't be able to use normal pen, because of nil-gravity, that the ink wouldn't drop on papers what ever the circumstances, so what did they do to solve this problem?!!!
They made a research lasted for 10 years and more than 12 millions Dollars to develop a pen works even with nil-gravity, not only that, but also to write on a smooth surface, even in a 300c degrees temprature
Another solution: when the Russian faced the same problem, they simply decided to use pencils instead of pens
Examply #2:
Once in Japan, and in a big soap factory, they had a big problem, which was the empty boxes that weren't full of soap due some wrong, so what did they do to recognize the empty and full boxes?
They invented a machine used X-ray to discover the soap inside the boxs, posed it infront of the exit-line in deliver section, and hired new employees to distract the empty boxes discovered by the machine.
Other solution:In other smaller factory, when they faced the same problem, they brought a big fan, adjusted its power to suit with the enpty boxes, so the empty boxes were in the air
Reslut:
Think in the resolution of the problem and not in problem itself
There're a lot of people who are very good making troubles from nothing, try to avoid them.
