In what ways can the rhythmic motion and repetitive nature of cycling be leveraged to cultivate a mindfulness that fosters gratitude and appreciation for the world around us, and are there specific techniques or practices that can be employed to enhance this effect, such as focusing on the sensation of the wind, the beauty of the surroundings, or the physical sensations in the body? Additionally, can the sense of accomplishment and self-efficacy that comes from completing a challenging ride or reaching a milestone be used to amplify feelings of gratitude, and if so, how can cyclists harness this feeling to appreciate the world around them?
