It sounds like you need to give yourself something to do that would require you to push your envelope a bit. Maybe learn something new that's likely to be difficult. Start some sort of project that's going to be a little bit of a pain in the rear, but not crazy.
Maybe take up BASE jumping like they do in Russia
