You need to buy some kitchen equipment, one or two of the good basic cookbooks like "The Joy of Cooking" or Bittman's "How to Cook Everything," and build a sustainable repertoire of 10-15 cheap, healthy dinners with a few variations each that you can put together easily and quickly.Better for your pocket, better for your mental health because it will help ground you, better for your love life because smart, capable people appreciate personal cooking skills in others.The top three expenses of the American household, as @Scott Trench's book taught me, are housing, transportation, and food.

It may have worked in 2010 but not in 2021.My suggestion would be to learn basic theory: cash flow, operations, marketing, wholesaling, notes, foreclosures, agency, law etc and then figure out what exactly you want to do, then seek out to launch and refine your method.There are cookbooks once you know what you want to do, but you dont need to pay a guru to spoon feed you.
