Dont know what went wrong. Please aqdvise, even if its rude

I am an MBA from India 99 batch, AVP with the multinational bank ( About to become VP ). Gave my first GMAT in November and scored 560 ( Q= 39, V = 28), and reappeared today for my gmat and scored 580 ( Q=37, V=32). TOEFL = 106.
Though i couldn't afford to take leave from work and study but really worked hard post office and on weekends, but still no success. I am doing good in my job and will surely keep progressing but its my dream to have MBA from top 10 and also to have international work experience. This is my first blog here and need advise from young people here to know as to where i am going wrong. I am a highly rated and regarded employee in my organisation. Get paid more then the average salary ( In terms of Purchasing power parity ) of harvard or LBS graduates, but still just want to fulfill my dream of Ivy MBA at any cost. I guess there is some insanity in all of us and i have my own level of it.
Please advise as i don't want to apply anywhere with these scores, not because of the fear of rejection but coz i am ashamed of these scores. Should i re-take it third time and if i should then what should i do to improve my score.

Cheers & Smiles !
