Focus on your breath

As you breathe in, follow your breath in through your nostrils, then into your throat, then into your lungs and belly. Sit straight, keep your eyes open but looking at the ground and with a soft focus. If you want to close your eyes, that's fine. As you breathe out, follow your breath out back into the world. If it helps, count...one breath in, two breath out, three breath in, four breath out...when you get to 10, start over. If you lose track, start over. If you find your mind wandering (and you will), just pay attention to your mind wandering, then bring it gently back to your breath. Repeat this process for the few minutes you meditate. You won't be very good at it at first, most likely, but you'll get better with practice.

And that's it. It's a very simple practice, but you want to do it for 2 minutes, every day, after the same trigger each day. Do this for a month and you'll have a daily meditation habit.
