It's so hard to leave....until you leave.

“And as paralyzing and upsetting as all the never agains were, the final leaving felt perfect. Pure. The most distilled possible form of liberation. Everything that mattered except one lousy picture was in the trash, but it felt so great. I started jogging, wanting to put even more distance between myself and school.
It is so hard to leave—until you leave. And then it is the easiest goddamned thing in the world.”
― John Green, Paper Towns
