I tried jumping 2 years. Once you overcome getting off and your in mid air there is really no going back. The only thing I learned is that it is extremely agonizing if you fail. I think extreme heights guarantee death but if you put much thought into it then you would end up backing out. The method of jumping I used was driving on the expressway until I got to an elevated enough point where I could see the treetops from the acres of land next to the expressway, once I pulled over I put on the blinkers, played some music to hype me up, and leaped for the most distance from my jumpoff point without an issue. I failed terribly though, had to walk through the land, crawl under a fence, get back to an interstate road, walk to the middle of traffic avoiding speeding cars, and pray that someone see me and call state troopers. I waited for hours but eventually state troopers stopped and got an ambulance to pick me up on a stretcher and take me to a hospital. Even though i survived with non life threatening injuries (fractured ribs, fractured lung, bilateral fractured wrists, fractured ankles, fractured pelvic, fractured nose, and a very deep wound near my eyebrow) i feel like ctb using this method is reliable from a great height. This is my plan b until I hear news about N. Since the experience was so bad I've been discouraged and kind of have to work myself up on overcoming it before trying again. Also because the thought of failing is always in the back of my head. Make sure your jumping from a very high place to make sure you can get your freedom. Best of luck!
