If you can get very efficient at it or you find the activity a source of leisure, then cooking your own food is a great cost savings. However, for someone in the tech industry the opportunity cost of not investing in themselves (i.e. coding, reading about code, meeting people, etc) for the same amount of time they are cooking (grocery shopping, food prep, cooking, cleaning, etc) usually isn&#x27;t worth it.<p>To me cooking your own food seems like a penny-wise, pound foolish thing. Of course eating out healthily multiple times a day gets insanely expensive, so that&#x27;s not really an option either. That&#x27;s why I&#x27;m a big advocate of soylent.
