You know that moment when you're just laying in your bed

and suddenly it hits you that in a month you're going to get on a plane all by yourself and fly to the other side of the world to a place with no toilets or clean water where you will try your best to make some lives a little better and make really great friends and see elephants and monkeys and sleep under a mosquito net and then you get those faint jitters deep in your stomach and your heart starts slowly coming out of your chest and then you think to yourself that your life is awesome?

Yeah, I just had that, too.
