Well, it's more than one thing but I don't consider myself as a prepper.

• I have a few months' worth of food both frozen and canned/dried/long lasting.
• I have enough of flour to bake a bread for a year.
• I have enough toilet paper, toothpaste, shower gel, soap, cleaning supplies, etc. to use it for 6ish months.
• I grow my own veggies. Between October and May I don't buy any veggies and for the whole year I don't buy spring onion, radishes and herbs.
• I know how to fix things.
• I know how to cook.
• I have several flashlights and radios with a crank (no battery needed).
• I'm about to install solar panels, wind turbine and rain water collector.
