Yea Odin has the idea.

When someone doesn't know what to do means they have ideas in their mind, but they aren't making it to thought. Running, working out, playing a game.

Anything that gets your mind stimulated and working again will gets things going.

An example: Usually when I don't know what to eat I end up just going to fast food. I get in my car and drive. I have no idea what I want, but I'm driving. As I drive I have to react to many things. This gets my thought process working. In 5-10 mins I know where I am going.
