Peregrine,
I do not equate being prepared with being unhappy or unfulfilled at all. I consider myself prepared, yet also happy and fulfilled. I also don't necessarily equate carrying a weapon with being "unhappy" or "unfulfilled". At this point in my life I generally do not carry a weapon...nearly never when I'm outside of the US. But when I did carry in the past I was certainly still happy, etc. There will certainly be times when I carry again, and I'm sure I'll be happy then too.
However, I do feel "better" not carrying a weapon. Having a weapon does suggest the possibility of having to use it, and you do need to be aware of your weapon. My decision to stop carrying coincided with the aftermath of Katrina when New Orleans became a very safe place for a short period. Although this period was terrible due to the physical situation in the city, it was also nice as we spent evening after evening out on the street talking to the few people who were back in the first few months. I started carrying again as the crime worsened. You may be right to some degree...it is possible that my association with carrying a weapon and "discomfort" is related to those circumstances...the fact that whenever I carried I did so because there was a significant chance of being involved in some crime. When alone, this was not nearly as uncomfortable as when I was with my wife.
You ask, regarding my feeling about weapons/preparedness: "Is it because you chose to carry a firearm based on your fear of your previous experience?" (I deleted the comments in the first post because I thought they related too much to the knife thread, and were a bit long for someone coming to this thread straight away.) I had many, many "experiences" with crime in New Orleans. I wouldn't say that I personally "feared" it, but the more I traveled to very safe places, the more I liked not having to be prepared in the way I was in N.O., 24/7. In the time I lived there, there were 2 shootings directly in front of my last house, 1 in front of another I lived in. My wife and I would hear gunshots probably every other night, whenever we didn't have the AC on. We'd hear automatic weapon fire probably once a month. Often you could guess who won and who lost. We had bullet holes in our roof on two occasions, we found shotgun shells in our backyard, there were several fights in front of our house, shootings down the street, a brothel two blocks away for a while, etc., etc...not to mention the bank robbery I wrote about and other family members being attacked...my sister was forced naked and robbed at gunpoint in her apartment, my mom was beaten and carjacked, etc. I could go on and on. My wife and I were prepared. I carried weapons; I had several stashed around the house; we had motion sensor lights, a motion activated camera, burglar bars, an alarm, and a dog. I wouldn't say I was in "fear", exactly because I was prepared. I was also happy. But, I must say that the crime and being prepared to prevent/deal with it put a filter in front of all else.
I hadn't thought about it that much to be honest with you. Like I said, I definitely don't associate being prepared with being unhappy, but there is a connection for me between carrying a weapon and being in an unsafe environment. Possibly that is why I feel "nicer" not carrying a weapon. I know this is hypothetical since everyone can't get up and move...but doesn't carrying a weapon suggest the possibility of attack? Would you not feel better living in a place where the odds are extraordinarily high that you will never be attacked? I certainly do...not even so much for myself but for my family.
Other points: I'm not sure what you mean by "meat eaters" carrying. I only know two vegetarians...most meat eaters I know do not carry.
I don't know how many people I've trained who were "on the ground", but there were several. I carried more than anyone I taught, and the military guys with the exception of two who were cops, didn't carry.
Finally, I didn't mean to suggest that you are not happy or fulfilled...but that you might feel a bit better if you didn't carry, or better put, if you didn't NEED to carry.
