Could be as trivial as a type of food, a TV show, or something more serious.
Awesome, if heights are still an issue. Try bouldering instead, it’s just climbing with no ropes and only up to 4ish metres off the ground (above soft mats for landing on if you fall).
It’s probably more popular than toprope (higher) climbing these days as its more accessible and can easily be done in groups of friends. Requires more strength and less endurance, but equally fun (more so for some people) as top roping.
It’s probably a very good way to get over your fear though, just having to jump from 12m with a rope does take some willpower initially but I don’t even think about it anymore.
