Spending time higher up also makes coming down to a lower height that much better. Train on 10M for a full day and then come back down to 3M and it seems like nothing. Was a good strategy to break your fear. One of my coaches (from Hungary) her father was her coach and used to dangle her and the other new recruits from the platform at a young age to break their fears. Not a strategy I would use with my kids, but worked for her (a 1988 Olympian.)
