There are a lot more than just these eight items that you can gather to keep your home functioning for your family as normal as possible, but for me, these are my foundations. However, what I have learned in using them is that I feel like I have moved a little more off-grid per se, in the sense that I am actually making my own foods, I am able to sterilize my own water, provide my own power and communicate without the need for a phone service. Sure, I have a lot more to accomplish before I am completely off-grid, but for the time being, my family and I are pretty happy where we are.
What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
