The notion that the difficult becomes possible if attempted in small, familiar increments encoded in the phrase “one foot in front of the other” is bunkum. At least for me these days. When I walk, I have to (try to) remember to tilt my pelvis a bit, shorten my stride, keep my chin up, keep my shoulders back, watch out for cross-traffic, avoid other pedestrians (Covid), avoid stepping in doggie bombs…you get the idea.
