We kind of think in terms of timing. There are events which require immediate response. Things like a fire, violent people trying to B&E, or a tornado. If the power goes out we've got some time to mull it over and contact the company. This summer we lost power at the cabin for something like 14 hours and didn't really notice. Grilled for dinner and let the kids make smores over the campfire. I drove into town for ice (I like a cocktail after fishing and cooking) and we were none the wiser.
I think a big hole in prepping is the soft skills. Knowing 3 nearby hospitals. Knowing your insurance agent if the house burns. Emergency contacts (beyond 911). Basic first aid. It's not too hard to do a thought experiment of 'what would I do if my kid broke her arm'? It's the sudden stuff you need to be mentally ready for.
Food and water... If you have some water and some food it's probably OK. If the whole family came down ill and nobody wanted to go to the store for a week would you be fine? Right now if I had to we could go probably a couple weeks with stored food eating really high quality. Risotto, paprikash, pasta served many different ways, red beans and rice, etc. My point is that I have a lot of dishes I could make on the fly and my family wouldn't even know we were in crisis mode. If you can eat what you like to eat for a few weeks you're probably good. Yes I have deep storage but it would suck to live on. This is why I believe in a proper "stocked kitchen". I always have at least 18 eggs, quarts of olive oil, 2 lbs. of butter, onions, gaarlic, jarred olives, canned tomatoes, etc. If I got snowed in tomorrow I could use canned chicken, olives, tomatoes, onions, garlic, and pasta to make a dynamite Sicilian pasta dish. Beats an MRE... But again it's the soft skill of knowing how to cook.
Guns... Take a class. Learn a new skill. Try 3 gun. I'm of the belief that you learn your holes by getting out and doing it. I spent the summer working on shooting longer range with aimed fire. Big hole of mine. I also think there is a MASSIVE hole in terms of procedure. If some big dude started ripping into your front door with a chainsaw who goes where and does what? Will you be able to communicate with 911 after discharging that .308 without hearing protection? Are you legally prepared for the aftermath?
Comms... I'll admit my weak point. The Ham Radio guys around here are really good at what they do and if I had more time I'd get into that. But have a plan to coordinate. If your house burned and you could call one sibling and have her do all the family contact so you don't need to make 74 phone calls and can focus on the task at hand it's easier.
I guess my takeaway is that I've never met a prepper who doesn't have enough "stuff". You probably have the basics down. Other than including first aid in the range bag (and I know you do that already, right?) most prepped people have the things they need. As I've joked before you could run to Costco and get 50 lbs each of flour and rice for probably $25. That's not a bad start. But a practiced cook looks at the flour and beans in the pantry and thinks "I can make homemade bread and hummus". I'd really look to the skills department rather than the stuff department.
