So...you drive a hot car...You remember when you first started driving hot cars and you had to be more careful? Let the clutch out calmly, don't stomp down on it, behave yourself, take the threat of the car serious? Then later, you got more relaxed and were able to drive the car more ably. That's what carrying a gun is like - you have to relax. The gun is a tool, like the car is. It's a tool for serious business, but then so is a car. And just like the average guy probably doesn't know you have 400 horses under the hood, the average guy doesn't know you have a 9mm on your hip. Wear your gun, like you drive your car, or wear your favorite pair of shoes - comfortably. If you have to change everything about your day-to-day routine to carry a gun it's too much of a burden.
And I know "carrying a gun should be comforting, not comfortable." And whatever...Here's an aphorism for you to mull over, "A wise man never feels out of place." And that means being alert, aware, confident, secure, and comfortable in day-to-day situations.
