I take hour-long walks around my neighborhood at least 4 times a week. This time is used more for brainstorming and reflection than a focus on speed and exercise. The physical activity is secondary, honestly. I feel better after the fact, but the real accomplishment is happening on my phone.
Instead of simply thinking about topics and hoping I remember the wording once I’ve returned to my apartment, I have taken to typing these thoughts into the notepad app on my phone.
