I could never handle writing a haiku...I tend towards rambling, too many words and not enough sense to figure out how to write concisely. Or count syllables. In such a brief period you've created a speaker with so much confidence and given the impression that the world is at his/her fingertips. It's well done and more importantly, every one has that day that they can relate to, when they were on top of the world, just ready to grasp the world, and take charge.
Similarly to jacoberin I like the fact that it can be interpreted in so many ways.
I saw it as a piece about confidence or like having a euphoric high and being able to reach the stars. Great piece. Relate-able in so many situations in life. This was definitely fitting when I got promoted early in the military, won a national drill meet in H.S.
