Seat in a comfortable position with your back straight in a quiet place. Close your eyes, and try to observe the way the air goes in and out of your nose for 10 minutes. Don't try to relax or achieve something, just observe. When you realize are not observing anymore for whatever of the 1000 possible reasons, which can happen quickly and a lot, simply try again without pushing yourself. The beauty of this exercise is that you can't fail. Keep at it regularly until you feel to take a more serious course with somebody experimented around you. Don't try to get anything special from it as meditation is very ordinary. Do not worry about you being bad at it or being boring. None of what you experience will prevent you from benefiting for it.
