What helped you overcome your fear of heights the most for climbing?

Lead climbing multiple times a week, this is what helped me overcome my fear of heights, at least while climbing.

I found a friend to climb with, and we climbed 3 times a week. The frequent climbing amount really helped boost my confidence in being up so high, and my confidence in the gear and the knots and everything else.

Though, this didnt last long, as soon after we stopped lead climbing so often, my nervousness came back, and so did the fear eventually. Now I lead climb once in a while, and its hell for me. The fear just takes over once I get to a certain height.

Maybe if I would have climbed more during that time I climbed 3 times a week, meaning, doing it for months or a year, then maybe I would be more immune to the fear of heights, but, unfortunately it only lasted about a month or two. But during that time, towards the end, I was fearless.
