Cooking. I don’t mean heating up prepared food. I mean taking raw produce, spices, herbs, and starches to make your own food. Doesn’t need to be extravagant. Start with an omelette or maybe properly made scrambled eggs. Move on to other “easy” dishes like grilled cheese sandwiches and spaghetti. I am constantly amazed when I hear fully grown adults saying shit like, “I could never make anything like Beef Wellington.” Yes you can, just try and fail a few times!
