To me, archery is challenging because there are variables such as wind conditions, arm and shoulder strength and steadiness, the drag between the arrow and the bow, the condition and orientation of the fletches on your arrow, and the amount of pull you exert on the bowstring. These are all things that an archer must adjust or account for in order to shoot accurately. I never miss any coverage of Olympic archery competitions if I can avoid it; the best archers are a treat to watch and I pick up a lot of tips from them.
People have many different ways that they meditate; some stand on their heads, some assume the Lotus position, a few hang upside down in inversion boots, while others just sit and woolgather. My method is to shoot arrows into targets as quickly and accurately as I can.
