Find a quiet and comfortable place where you can sit and relax for ten minutes. Fully focus your attention inwards and watch your thoughts. Think of your attention as a bright light bulb instead of a laser pointer. Instead of following the thoughts that come up, keep your attention broad and wide. Sit back and watch all the thoughts pop up, float by and eventually disappear.
Tipp: Judging the thoughts that come up is engaging. Rating your success with this exercise is engaging. For the duration of this exercise, don’t engage and simply watch!
