Maybe you can afford to wait. Maybe for you there’s a tomorrow. Maybe for you there’s one thousand tomorrows, or three thousand, or ten, so much time you can bathe in it, roll around in it, let it slide like coins through your fingers. So much time you can waste it. 
But for some of us there’s only today. And the truth is, you never really know.

from Before I Fall by Lauren Oliver

It amazes me how easy it is for things to change, how easy it is to start off down the same road you always take and wind up somewhere new. Just one false step, one pause, one detour, and you end up with new friends or a bad reputation or a boyfriend or a breakup. It’s never occurred to me before; I’ve never been able to see it. And it makes me feel, weirdly, like maybe all of these different possibilities exist at the same time, like each moment we live has a thousand other moments layered underneath it that look different.
