I believed as we grow older we solved mistry of dichotomy nature of life. In fact we get more and more confused and wonder what exactly we wanted in life and is it correct we led our life? When you land up in urban life, you crave for rural life. In my case I wish for jungle life!! But if you go close to rural/jungle life you wonder when you will return to urban life.
When you are alone you want to be with many people and other way round.
Why we always feel something missing all the time? I think this is the irony of human life which in one sense helps to conquer odds which are lied on his way and other hand makes him reckless to get it.
