Whats life about anyways!!!!

As you know, most of the people pass their 12th grade and then go for engineering or medical or mass comm or.......the list never ends. But a question that seems to trouble me all the time is that "Is this why we were born, to become engineers or doctors etc??". Like fine I m going to an engineer in about 3 years, but then there are engineers everywhere...slogging their balls out to either create or improve or doing anything related to their field. I make something remarkable, people applaud it...my work is appreciated..then everything is forgotten!!!!My recognition slips into this grave of Oblivion...Then i started working on something else....is this life all about??
When our studies are over, we'll be running short of time for ourselves and for the things we always wanted a do. Things or rather missions that we always thought of undertaking.....be it holding a pool party or trying to woo girls in a restaurant(DJ knows what i am talking about!!) ....we had all the time in the world to do these.....but fell short of finances. However when we start working we'll have the money...but time....no where!!! So is life all about regretting on things we always wanted to do but couldn't. Or is it about cherishing your moments of true fun. One more things I'd like to say is that the often used phrase "LIFE IS SHORT" is a piece of unimaginable and futile shit, Life is what we make it......Most of your teenage is spent in finding and trying to impress the girl of our dreams and the 20s in trying to find work, 30s in trying to make a living for oneself and family and so on. You know what the problem is....we hardly decide on anything concrete....fickleness seems be our inherent quality.(Ever wondered why most of the planned party, remain just that??i am still wondering!!) So i would like to end this piece of Dhruv balls by asking you'll one question....What did you always want to do?? Think what your life is all about???Tell us about it!!!
