I think all over the world there is a believe like ‘You should be stand infront of the bad thinks, you should resist to damages.’. It can be for everything. The idea is you should always resist to everything. It use often in the sport also. Because when you want to be succesful you should be suffer. This is the main purpose for the great sport players. Moreover if you are in your comfort area you never be succesful. Also Usain Bolt is a big example actually. He trained for run 100 meter under 10 second his entire life.
So when you look at Usain Bolt, he always train his all time and just suffer. But he is the greatest runner of all time. Maybe he feel embaresed, angery or tired in some parts of his life but after he saw the medals he started to feel that this suffer is good and worthy for what pain he felt before. Moreover after he started to run nearly the world record he would train more painfull but more usefull for his running. After when he broke the record the real responsibilty was started. He should back up this nickname, world record holder, He should breake the new world records. On the other hand he made it. He was create the greatest runner of all world.
On the other hand not all humans can make this . Two types of them actually. One of them is when they are start to train hard they injured. After injur the sproters can not make hard training or they leave the sport. Also they can be more determined after the injurity. This is the part that you turn the bad position to good position. You use your injurity and develope more but if you lie down on bed you never be a successful person . Some of the other people are can not stad and leave the sport.
As a result suffer from the pain is not always bad for life. For being different and successful you should be out from your confor area. You should be in painfull and unwanted life. This is not mean just physical, also physicologicaly you always feel oppression. These can be your family, your choach, your neighbours or your country. They always want more and more from you. That is the big part of the oppression. But when you resist to these opressions you become the real sporter. So for being successful you should be out from your comfort area.
