I'll be the first to admit it, my current life plan isn't spectacular. I won't be graduating with a bachelors' in three years, and I probably won't have the money to pay for grad school after I do graduate. I'll be lucky if I have a job by then, and I'll be able to support myself (and my college bills eventually) but that's about it. I'll be working weird hours, traveling a lot and doing things that might make people mad at me. Seems like a pretty fruitless outlook.
But it is our job to tell someone's (or something's) story, and when you get personally thanked by a complete stranger for your work, it's a pretty damn awesome feeling.
