Existentialism

It's actually been a while since I last hit upon 'my' site! So tonight, I decided to give myself some time. I have been in London for more than six months and sometimes it feels like an era...and at times, I feel like running back to what I left. And then there are times when, in the hustle bustle of 'life', you just forget to live. Am I living? I mean yes...breathing, eating, sleeping, working, and doing the normal things. But the question is: Am I living my life? Or am I wasting it fearing about the future, contemplating about the present and recuperating from the nostalgia of the past.
So what next? And therein lies the mysteries of existence...what tomorrow holds, you'll never know today, and if you do, then what's the point of living tommorrow. Vague? I am.
