What next ?

I am perpetually afraid of the question"what next?" I might have completed reading the nth book. just returned from the holidays those were always overdue, came out of the cinema hall watching the movie that I longed to view for aeons. and the question? ! so I have seen all, done all, at least the feeling is there, what next! Is it to do something with 'being'? I exist, so I exist! And I exist, so I have to do it all, all the time. After reading umpteen books did my 'being' got more mature, more experienced, more profound? I don't have answers. After seeing a thousand movies, visiting many countries did my horizons widen? I don't know. And if they really widen. what's the limit for widening? What's the motive behind zest, rather motivation itself? I don't know, probably utter confusion may be the limit. I am not philosopher, trying to put my feet in Buddha's shoes, nor I am pretender like Mahesh Bhatt who has all the answers for everything under the sun. But what are the 'achievements' themselves? what are my gains for 'being'? I call myself a man of science but I won't be able to tell, who was the Nobel laureate in Medicines for last year. But I can enumerate 'n' no. of Gandhis, including Rahul !!!. Who is more achiever? A Gandhi or a Nobel prize winner? Am I going to leave imprints of my being on time? If the answer is no, the whole rhetoric seems futile. No, I am not depressed nor going to stop living the next moment nor longing for early death, but many a time I wonder what's the propriety?
