Yes, because they were the best photographs I will ever make. A legend in my own mind and all of that.
Seriously though, I have passed up shots because I didn't have the time right then, or some other conflict, went back later and the thing that had attracted my attention had been moved, destroyed, etc. Or the light was never the same again. 2 summers ago while shooting in South Dakoka I passed up a picture because I had been shooting all day and was very tired, plus it was a different subject than what I went there to shoot. It has haunted me since. I have convinced myself that it would have been the best image of the trip.
I have read that Dorothea Lange drove 20 miles past a sign that caught her attention, but finally gave in to her internal voice and backtracked, where she found the picture that would come to be known as "Migrant Mother."
