Every Thing Happens for reason...?

Life is full of surprises. Every other day something happens and we evaluate it on our own sight that whether it is good or bad for us. At times things happen which for instance seem a bad thing to happen but as time passes by that thing might have saved you from a lot of other problems. But does everything happens for a reason,everything has some message for us and others.Have you ever thought of it?
Few months back a plane crashed in the hills of Margalla (Pakistan). Many people were killed in the crash and it was termed as the biggest crash in the Aviation history of Pakistan.Almost 13 people got their tickets cancelled due to bad weather,and were lucky. One MNA who needed that flight was denied as the flight was "FULL".He tried his best to get in but he did not succeed. Wonder what he would have been thinking after the crash.This is just one incident but try to look back at your lives ,there may have been many instances where something you thought went wrong but later turned out to be your saviour.
Now lets have a look at other side of story.If you will keep on thinking that whatever is happening (good or bad) is supposed to be in your favour and you quit exerting your effort,then the result will be no more different than what we are observing today. We are becoming ethically dead day by day. There is a blast every other day and the government's responsibility seems ti end by saying that Taliban are involved in it,everyone forgets it the very other day. In our lives we are not honest,we lie to earn more and we to get a bigger profit margin even if it is at the cost of others rights. We try not to respect the signals because it is easier for us to bribe a policeman than to go and wait in queue and submit our ticket. The list can go on and on but wait. Is this Happening for our own good. Are we not trying to hammer an axe on our own foot, what will be the end result??
After the earthquake of 2005 and floods of 2010 we are still paving our way towards wrong path. Has it not taught us anything. Are these warning signs not enough for us to mend our ways. Are we waiting for some miracle to happen or are we living in fools paradise by thinking its for our own good?When will we start thinking on right path....
