I FEEL DISSATISFIED.WAT TO DO?

well dis year i have applied for mba and i have an institute finally in hand.now i couldnt score the best in my entrance and so couldnt get the top institutes bt considering the killing competition and how some lucky students just get thru i still find myself lucky enuf to be getting a seat in a decent college.now i am a fresher and have always wanted the best institutues to study in,as luck wud have it its been a tough 1 year and honestly i have never put in so much of hardwork as i have in the past 1 year.so now i still want the best for myself ,i hear of randomn people in better institutes and feel well have i missed the buck ,maybe i wount be able to be a part of dat circle .i am very ambitious and i will get a good job down the line i noe,so should i feel dis dissatisfied.i cant stop compare sometimes.after all u r competing with d best .
