I started running a couple months ago, I do my best thinking now while running out in nature (running in the city is not as good, too many interruptions). I've set my day up so I can go straight to the computer after I run without changing out of my running clothes or doing a bunch of transitional tasks, because that time is cognitively valuable. I'm full of ideas and want to get them down before they fade. Running takes up about 2 hours of my day, but running for 2 hours and working for 4 feels more productive than just working for 6 hours. I'm doing better work.

I was once obsessed with climbing for almost a decade. When climbing I was 100% focused on climbing, my mind wasn't really free to wander and think of other things. Even when I was done climbing, I would still be thinking about climbing. Climbing problems were always the biggest problems in my life, they had a way of eclipsing everything else, which is what it means to get the 'climbing bug'.
