I wouldn’t worry about clocks or watches, but Qi Gong can help you remain centered and maintain vitality. It will also improve awareness of your body to help you avoid unhealthy motions which can lead to injuries or exacerbate chronic conditions. There was a summer where I practiced qi gong in time with the day: dawn, noon, sunset, and midnight. It was a very powerful practice and I benefited a lot from it. But the benefits are not tangible, they accumulate slowly over a long period of time. Cultivating qi is like weeding and watering a garden. You don’t see the result until many weeks later when you the harvested fruit is bigger and healthier. Major keys to studying qi gong (from my experience): 1) Focus on your breathing first. Qi flows from the breath. I recommend ignoring complicated motions until you have centered and regulated your breathing into long slow inhale/exhales. 2) Time movements with breathing. At first this requires some effort, but soon becomes natural. 3) Make movements as slow and smooth as possible. This requires patience, but your awareness of qi is improved a lot by paying attention to this one. 4) Relax as much as possible. Really practice the “standing null” position. Learn to keep your joints bent, but strong. Keep your shoulders, neck, and face loose. Keep your spine straight and your weight balanced in the middle of your feet (or slightly back towards the heels), not on the toes. Keeping your legs soft (while still standing) is the key to moving qi through your legs. Keeping your arms soft (while moving) is the key to moving qi through your arms. Good luck!
