Excitement:

I've realized this summer and now through this first week of school how overwhelmingly excited I get when I think about my career choice and learning about how to do it well. I was flipping through a booklet advertising something and it was done so well that I got really excited and even started to shake. Even reading my marketing homework and gleaning business stragies from it made me very thrilled to be studying and striving towards this graphic design goal. These are good times when my confidence is overridden by my excitement. It is such an amazing feeling to be chasing a dream. Wow, that sounded really cheesy, but I really meant it.

word of the day that I actually used (correctly) without even thinking about it: precarious
oh yes, I was excited about this usage.
