I have a history of getting prepared, and then "backsliding".
Way back during the Y2K event, I was very prepared: we had weeks (even months) of non-perishable food stockpiled; we had lots of bottled water stockpiled too, but also had purification tablets on hand in case we needed to start using water from our swimming pool. We also attended a seminar put on by some local wilderness trekkers who taught us some amazing survival skills.
Once Y2K came and went with a whimper, we eventually worked through our stockpile without replenishing it. We moved across the country not long after and gave away the rest.
We had more room in our new home, and I again stockpiled a lot of nonperishables goods. This time, I matched it with the regular foods we ate.
For example, we use a lot of canned tomatoes and pastes in various recipes, so instead of buying a couple of cans of tomato paste, I would buy a couple of cases. I dated each case and would rotate them so that we were always pulling from the oldest stock. Once we finished a case, I would buy another on the next trip to the grocery store so that at any one time, we had three or four cases of tomato paste on hand. I did the same thing with canned vegetables, canned fruits, soups, etc.
After a couple of years, however, I backslid on doing that.
Right now, the only thing I've done is put together two "get home" bags (as opposed to "bug out" bags). I have one in my car and one in the wife's. They just have some basic survival gear (emergency blanket, flashlight, warm clothes, etc.) in case there's some kind of disaster and either of us is stuck away from home
