Grow Your Own Food
Reddit user YYYY says:
"Learn to grow . . . food. It is not hard, and you don't need a lot of tools, either. I mostly use a shovel and five-tine fork. I don't plow, till, or weed — because I don't have many weeds."
And if growing your own food seems intimidating or if you don't have a garden, start by growing herbs in your kitchen.
