Hope in Despair !!

I have now finished CAT and all other competitive exams. I came close to cracking a few of these exams but missed the cut-offs of almost all of them. After having so called "failed" these exams and unable to get that most coveted seat in these highly desired Management Institutes, I was filled with despair.
In fact, I still dont know what my future holds for me. I have various plans now.Such as "trying again for these exams" or "working and then give a shot to these exams". More importantly, I don't understand why I could'nt get through these exams. I thought that I had worked hard. But when I saw others scoring much higher than me,I realised that my evaluation of my efforts was nothing but a grim illusion.
I have firm belief that every person is capable of doing everything. If 1 person in the entire world can do something, anyone else can also do it. For example, I truly believe that going on the moon is possible for every one; efforts required to be there may be differently required. A genius would take a lesser time and averagers (like me) would take a (lot) longer time. BUT, its possible. Moreover, the tougher for a person to achieve something, more enjoyable the success becomes.
Ultimately, its the effort, determination and belief is what counts. Never lose heart as thats the biggest loss.As long as there is life,there is hope.
I am trying to reach to the elusive seat of those management institutes and shall try until I get that seat. And when I get there, I shall set higher goals. But for now, that seat is my LAKSHYA ( hindi for target).
