I determined a long time ago that I will probably go through my entire life and never need
my gun. However, if I'm ever proved wrong, these two things will likely be true: I will need it very quickly, and I will need it very badly. Hence, I carry nearly always.
Slightly of topic, but here's a theory I have, for which I have absolutely no evidence but common sense. It's been shown that critters read the "body language" of potenetial victims and tend to steer clear of those with an alert, self-confident attitude. Seems to me that those of us that carry, whether we realize it or not, probably display those traits, mayhaps avoiding trouble without any conscious effort on our part. Then again, maybe I don't know what I'm talkin' about...
