If Peace Corps gives you nothing else, it gives you time to think. If you leave your 27 month commitment without strong personal convictions worked out extensively in your mind, man, you must have been watching a lot of re-runs of The Office (and West Wing, and House, and Family Guy, and...and...and...). In the immortal words of Fred Quinn, "...not that there's anything wrong with that!"
Great post- a majority of our job in the Peace Corps. is cultural exchange... And we do manage to make differences in the lives of those in our host countries, just in different ways. I took me a while to realize while, I was sent to Ukraine to teach. What I'm really here to do is learn.
