life.........

life.......as we all know A thing which god has given us to use it to its full potential in improving the earth.but the question is how?????whenever we lose in our activities god just wants 2 say tht we havent fully tried in accomplishing our work and y do we change our emotions whenever we win or lose in life??we should accept them as them come,calmly.It is possible 4 us 2 accomplish anything in the world only if we keep our mind 2 it.we can change the world only if we have the mind to DO IT.sometimes i feel god has sent me to earth to watch the sins done by his own creations Ex:killing his fellow beings.But 1 question keeps repeating in our minds y does he do it???
