Life is Complex!
Whatever you are thinking and whatever you are planning may or may not go the way you want it to. Why is this so? Have you ever thought that planning for a coming function which took you a week ,a month or a year to plan never went the way you wanted it to? This is not because you were wrong , this is because of the fact that life is complex and all of the event that are happening in life are closely related to each other and are happening one after another with close impact of one on another. This is both beautiful as well as think full to have such series of events going on all the time around you.
