Get out and do boring things. Your mind will fill up the dead-space with creative ideas.
Go on walks.
Hike.
Go on long road trips.

Sometimes I record my thoughts out loud. But for the most time, I just use it as a way to keep my mind churning. Sometimes I come up with new side projects, or a design for a new piece of furniture, or just wonder on certain things (friends/family, state of the world, the guy that coughed on me at the restaurant).
I consider saddle time "taking my brain to the park" so it runs around for a bit and tires itself out.
I've been calling it "urban hiking" and everyone thinks I'm joking. But why drive all the way to the wilderness to do a hike, when I can just walk out the door?
