Learning to garden and understanding how to process / store seeds and long term vegetable storage (freezing, dehydrating, canning, etc.) is a great start. I’ve been prepping since pre-Y2K and only the last 4 years was able to transition to longer term solutions. All the rentals and contingencies prior to buying my property was in preparation for when I could. I had gardens at almost every home in between and chickens when I could.
