Trees in a Forest

Lacking a compass, an old scouting trick is this... If you're lost in a forest, unsure of the way out, or even what direction to move, you locate three trees in a row. One close by, another a little ways away, and one farther off in the distance - all in line with each other. And you move from one tree to the next, picking another tree farther down the line each time that you progress.

That's a literal interpretation: actually finding our way out of a forest. The generality applies to a variety of decisions. We may not know the right path, but there's only one way to make progress!
