Heights never worried me... after I got tossed out of uni, I worked as a window washer on high rises... outside, not inside... till I came down to earth and got a normal job.
It's just old age and a few unrehearsed swan dives off the top rung that made me a tad scared when I came down to earth these times.
If your first cut is too short... Take the second cut from the longer end... LBD
