How else can I define it? I fall short of words to describe the moment that's coming in a few hours. It will be erroneous to describe my feelings as ecstasy. What I am feeling now is something I've rarely, or maybe never experienced. It's not elation, it's something beyond that. It's that something plus anxiety, fear, anticipation, awe. Now that would be a more apt description. I think I have written ample words trying in vain to do what is beyond my ability.
Let's get it straight. How would you feel if you were an astronomy enthusiast and got to express yourself in front of the top astronomers of the world? How would you feel if you were being featured at the convention where world's best astronomers meet and where every major decision about astronomy was made? How would you feel if you got the chance to represent your nation, acknowledge the part of the most important people in your life and say what you want to at such a convention?
See? Don't all these feelings obstruct your thoughts? Oh, I forgot to add: how would you feel if the highest governing body in astronomy gave you an award for your work when you are still in school?
