My day at work Exhilarating? Euphoria? Wtf?

Sometimes I really hate my job. But overall I need to remember that I'm lucky to have one, one that pays decent and has fairly decent benefit

  I love the fast pace environment where I'm solving problems one by one and sometimes more than one problem at a time. I actually got a chill today of excitement, if that describes it properly   , maybe the right word is euphoria or exhilaration. 

 I love looking back on the day and seeing that I've made a difference .
