a question that makes me question my abilities!!

interviewer: hi Shreyas.
me: hi..
int: tell me something about yourself.. 
me: ????????????????????????????????????????????

i have never come across a commonly asked question than this which brings plenty of questions about yourself, your ability in your mind! who am i? a question that haunted KARNA his entire life.. if he would have agreed to what ppl around him, mahabharta would have been an entire different story. but he fought.. he fought for himself and with himself to prove who he was.. a great warrior .. a pandava..was the easy answer to his question. he proved it with krishna's help at the end.
karna is an epic ancient character..   but who am i? whats my worth ?
as one of my dearest friend says i have two professional degrees. but are they worth it ? have i learn anything from it ? trust me . i have no answer..
the only thing that i know is my education has made me tough.. practical.. n logical thinker.. have rooted ethics in me.. and have made me one responsible, educated Indian Citizen ..
what else i have? nice parents?? its a god's gift.. roti kapda makan car.. my parents' gift..   relatives.. again inharited..!
the only treasure i have .. that i have accumulated over the years.. are my friends! they are the diamonds i have in my collectibles!
i think this is where am different than karna.. i knw who i am.. i knw my parents .. i have my friends..

so the only unanswered question will be whats my worth?? am finding the answer...
i think i'll find the answer till the eternity.. please somebody then post it back to all my interviewers..
