The best way to prepare is to ask questions that actually can be answered. A possibility would be to describe WHAT you want to prepare for. I know it's not that easy to think of that when asking something like this but that would help. Alternatively, to properly prepare do as follows: Buy a rope, not too thin, and a hook. Then attach it to the roof of your room and knot the rope on it. Before you do that don't forget to make a sling out the rope. Now you're prepared. Just put the rope around your neck and jump from a chair.
