I was also in those 10% but Remember one thing.. hard work, will power, dedication and perseverance are the key to success. None of my friends ever paid any heed to what I wanna ask them and to clear my queries. Since I wasn't physically well fit, I wasn't aware of any examinations, and all, and so my friends at school took it to their advantage, and never made me aware of them. I'm having the problems due to those only, and perhaps my dream couldn't ever be true do to their mentality to defeat me. Okay well, they are in IITs nice, I prayed for their succees. Whenever I went in between them mainly for Problem Solving, as Friendly discussions are just beyond my thoughts, to gather when they happened, they always made a fun of me because of my inabilities, both physically and mentally (numerical solution). So just, u all don't feel bad. It's worst when your dreams are shattered by others, like my friends at school did..since they used to tell about the examinations to all others, except me. I know it's hard to believe...yet it's the truth. So I am just trying to fetch the beads of my life's rosary, some of which have been shattered by the ravages of time, and rest been thrown to infinite distance, by my friend. So if a person like me, can have a subtle taste of those concepts, then u all are just gifted with GR8 lives by GOD...so just u have the work to shape it meticulously, as the potter's wheel is in Ur hands. All the best!!
