> What I didn’t expect was how difficult it would be. Sitting for 5-10 minutes staring at a wall without thinking of anything is hard! I relate it somewhat to the feeling I have with working out.

So why not combine working out directly instead of staring at a wall? Ride a stationary bike at low zone 2/lower in my experience allow for uninterrupted focus during that time at work. While on bike, the mind shuns distraction and focus on "what's next" in the workstream (distraction includes HN, evidently I haven't gotten on the bike yet).

My homeopathic theory is that I have a total mental energy that is the sum of focused energy and a distracting energy. This distracting energy can be temporarily used at task at hand but it results in mental exhaustion, or left alone it leads to distraction seeking behavior. While on the bike, distracting energy is fully consumed by riding, allowing for focused energy stay focused. If I go above low zone 2, it starts eating into focused energy and I lose efficiency.

Zen meditation for an hour staring at a wall is a marathon that at the end results in a semi-psychedelic state for me.

Exercising and sitting b meditating are two related but seriously different things. Which is why there are many other types of meditation to practice (walking, working, silent, etc) but zen mostly considers sitting and looking at a wall the OG
