The trick with Sneaking is in the footwork. What you need to do is roll the heel to the toe, making sure the center part of the foot does not touch the ground (hint: this does not work on gravel or leaves; see below). Try to find areas with living, not dying, grass for outside, and for inside stick to carpeted areas and avoid any objects that leave a print (i.e. dragging your foot on shaggy carpets leaves a streak). Only use these skill if you plan them with a friend, do not use them to break into houses and steal stuff or other illegal things.
