Some of the discussion here reminded me of when I was a certified motorcycle instructor and we were discussing the concept of "ATGATT", i.e., "all of the gear, all of the time" regarding protective clothing, helmet, boots, etc. I used to say to the students that obviously some riders were smarter than me, because I see them riding in shorts and flipflops, so they must know what days they are safe and what days they are going to crash.
If I knew what day and where I would need a gun I would stay home that day and not go anywhere. But obviously none of us knows when a totally quiet and ordinary day will turn into a life and death situation. I usually do not carry at home, and the other day I needed to run out for a few items to the grocery store. I left the house and arrived at the store and suddenly realized that I had not taken my gun. Fortunately everything went as normal and no gun was needed, but I was very aware that I had left myself vulnerable because I had forgotten that I had put away my gun when I came home earlier. This will probably get me to carry in the house now, all the time every day.
That said, I do know several people who like myself applied for and received their concealed carry license as soon as it was possible here in Illinois. But while I carry every day, I have a few friends who admitted that they have yet to carry. Reasons range from needing a better holster, needing a smaller or lighter gun, waiting until they retire since they cannot carry at work, etc. Each to their own.
