However, its important to protect yourself from the mentality of becoming paranoid and looking at everyday people as a threat constantly.
Correct. Besides the obvious issue, this kind of an attitude would be extremely stressful. The mindset you want isn't the idea of looking for threats constantly, nor is it the idea that you can dismiss any possibility of a threat. The balance is remaining open to the idea that bad things can happen anywhere. Not EXPECTING them to, but just not expecting them NOT to. This will help avoid getting yourself into a situation where you don't have the ability and/or mindset to respond effectively and rapidly should the need arise.
There have been a few over the years that I have suggested them not carry for 2 or 3 days just so they can get a grasp on reality.
The two things are not mutually exclusive. A person can make a commitment to carry anytime they can legally do so and still have a firm grasp on reality. If a person is starting to have issues with reality, the problem is a mindset issue, not the fact that they have a gun on them.
Carrying a weapon while doing yardwork in fear of other people is a little extreme IMO.
This is what is called a "snuck premise". It assumes that the only reason a person would carry is because of fear of other people. Preparation can be done simply out of a desire to be prepared without any fear being involved at all.
My love for firearms has zero to do with CCW.
I've always loved shooting and anything involved in shooting. Firearms, airguns--any kind of projectile dispenser. I learned the carry laws because I didn't want to get in trouble when I transported my firearms; I learned the self-defense laws mostly because I'd heard so many different things from different people that I wanted to know the truth.
One day I realized that I had spent a lot of time building skill and learning the laws and it would be really stupid to have that skill and knowledge and then end up in a situation where a firearm was needed and not have one. So I started carrying. It was easy to carry and hard to come up with any useful way to predict when having a gun might be needed, so I decided to carry any time it was possible to do so.
I've always liked to be prepared. I carry a number of potentially useful items--a multi-tool, a flashlight, a pocketknife, a compact magnifying glass, etc. because they come in handy from time to time and a gun is just one more potentially useful item. When I can't carry for one reason or another, I don't get jumpy or nervous or fearful--I know the odds of anything bad happening are really small. But the other side of the coin is that having two improbable events line up is way more improbable than just having one or the other happen independently. So it makes sense to make one of the two things (carrying) as probable as possible to maximize the chance that IF something really bad happens, it happens when useful tool is readily available to deal with the situation.
Frankly, the way I live my life, I'll probably get through the rest of it without ever needing a gun again. It's a nice goal.
