For me, it is easy. It is called
laziness.
I am willing to undergo a certain amount of discomfort and inconvenience to carry a firearm for the off chance I may need to defend myself. I do not carry extra magazines, CS gas, tazers, batons or other non-lethal weapons, not because I think I may not need them, but because it would be a pain in the butt to carry those concealed in Florida with 100F weather. I do carry extra ammo in my vehicle.
