Venting Frustrations

I'm having an edgy day--the program that I'm working on is giving me more trouble than usual (in ways that are counterintuitive to me) but since yelling at it doesn't help, I'm going to rant about something that a different supervisor just said.

So yes, actually, I am here to have fun, and I don't understand people who settle for anything less. I understand people who put off finding a fun job for a few years due to other circumstances (e.g. my working for the Justice Department--it had its moments, but it really wasn't for me; I stuck it out because of my scholarship obligation) but if someone isn't doing something they love or at least working towards that, I just don't get it...
