In a post-SHTF environment, being armed everywhere you go is a good idea. We can't predict exactly what our society will be like, but we know that violent people are not going to decide that they should give the rest of us a break because we're busy dealing with huge problems (no food on the store shelves; mass panic; a highly contagious disease; whatever). These people are already preying on victims, which is why I have a CHL and handgun in the first place.
Ideally, you live someplace where permission slips to bear arms are not required. A few parts of the United States have that going for them, but I like Texas for lots of reasons. Staying here and having my CHL is less than perfect, but I love being here and will continue dealing with the license-to-carry nonsense. At the same time, a lot of us are pressuring our Legislature to do away with permits and let law-abiding citizens carry handguns without taking classes, paying fees, and waiting for our packets to process.
Some of my advice won't necessarily apply to you. Feel free to take what you can use and leave the rest; I'm going to generalize so that the maximum number of people will get something useful (I hope, at least).
