I've also found walks to be super valuable. They're times where you can't get distracted because there's nothing else to do but think, like in the shower (which is why so many great ideas happen in each). They also get a little physical activity into your day which helps the brain work. When I take walks with my wife we have great convos that won't happen on the couch when we're exhausted. We walk this circular path around Duke's East campus, which is about 2 miles. Having a defined path like that helps too- you don't have to get distracted by where you're going or be temped to end it early.
