On a team video call, everyone said I sounded like I was in a tunnel. I messed with all my audio settings for like twenty minutes. Then I saw the big fluffy armchair right by my desk. I guess it was soaking up all the noise from my mic. I pushed it into the corner and my voice came back clear. Felt pretty dumb for not thinking of it earlier. Now I always scan my room before hopping on calls.
I started eating lunch at the same exact time every work day, and it really helps me build a routine. It stops me from grazing all afternoon and feeling sluggish after meals.
