It's good to make mistake, and here is why.

  1.   It’s always good to try new things because when you are trying new things you are growing. If you never try anything new, how can you improve? How can you expand? How can you innovate? The simple answer is "You can't". Look around you. With very few exceptions, either everything you see in your physical world or every single detail of every single thing is the result of someone trying something new.

Another good thing about mistakes is this.  2.   Consider this: Edison failed 10000 times before he perfected the light bulb. When asked how it felt to fail that many times, he remarked that he hadn't failed 10000 times, but rather had learned 10000 things that didn't work.

Finally, when you make a mistake you are much closer to success. Why? Because when all is said and done, you will have tried some limited number of things before you succeed.   3.  

But this all doesn't mean that you should go ahead with disregard for the consequences of a mistake. Quite the contrary, you have to be willing to set some reasonable limits if it doesn't work out the way you want it to.   4. 

We all have limited resources in the form of time and money, so don’t blow them all on one approach to a problem. Realize that it probably won't be perfect the first time and allocate these resources appropriately so you can learn, modify, and try it again. Only by embracing and using your mistakes in this way can you make significant advances in your business and your career.

There is an old truth that goes, "  5.   ”

So go forth and make mistakes. And learn. And grow. And prosper.

A．First of all, mistakes are a clear sign that you are trying new things.

B．Only those who do nothing make no mistakes.

C．If you're not making mistakes, you're not trying hard enough.

D．When you are making mistakes, you are learning.

E. You should take mistakes as stepping stone to future success.

F. You should guarantee you will be in a position to succeed again.

G. Every time you made a mistake you remove one of those things and are one step closer.

The 2012 London Olympics had enough problems to worry about. But one more has just been added -- a communications blackout caused by solar storms.
　　After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.
　　Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
　　"The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
　　At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. "A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is the greatest during a solar maximum when there is the greatest number of sunspots.
　　Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
　　The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.
　　Professor Richard Harrison, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advanced warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.
