As you breathe in, count “one,” and as you breathe out, count “one” again. Then “Two/two,” “Three/three,” until you arrive at ten. After that, go back in the other direction: “Ten/ten,” “Nine/nine,” and so on, until you arrive back at one. If you don’t get lost, you know that you have good concentration. If you do get lost, go back to “one,” and begin again. Relax. It’s only a game. When you succeed in counting, you can drop the numbers if you like and just say “in” and “out.”
