Sit with that empty space
You go out in the wilderness and prepare to think important, productive thoughts about what you want to be when you grow up and the kind of mark you're leaving on the world. And sometimes instead of thinking all those thoughts, you sit for hours and let your mind rest, empty except for the wind and the stream and the raucous chatter of Clark's nutcrackers. And that's okay.
Sometimes you have to sit with that empty space, become familiar with it, before you can fill it.
