I just got a masters in Climatology. Now I have a job doing important, socially and environmentally relevant work. My job helps people, and pays OK money.

And you know what?

I have to bust my ass and work like 60 hours a week, and stare at a computer all day. I should have waited another year or two, and enjoyed myself working to teach kids to fix bikes, or messenge, or other similar fun job. Be careful of getting a degree in order to do something important, because once you have a job that you are forced to care about, it will eat your life. And if you don't care about it and slack off, you'll (rightly) feel guilty about it.

I may cop out one day and go for a PhD so that I can get a nice professor job. Then I'll have sabbaticals, summer vacations, interesting research, fawning undergraduates, and be able to live in some hippie college town.
