All these things.

"Ever wonder how long it takes to change your life? What measure of time is enough to be life-altering? Is it four years, like high school? One year? An eight-week walking tour? Can your life change in a month, or a week, or a single day? We're always in a hurry to grow up, to go places, to get ahead... but when you're young, one hour can change everything."
