this is solid advice. you don't even need to hang from a ledge. just get good and high. and stand on your tip toes on top of a tall building's roof. I used a 6 story parking garage that I parked in at my last job.

once every 4-5 months I'd climb up there, stand on my tip toes, look down and scream I want to live.

i'd have nightmares where I was falling to my death for the next few nights. but I usually felt more confident in day to day settings after that. If you live near real life cliffs out in nature. I think it works better. because you don't get the random asshole that pops up at the wrong time, and is all like "don't do it man, its not worth it, think of your family"

I'm like....... I know. I'm just doing a drill here dumbass
