I've got some drafts in the oven as I continue my Halfhaven writing, but nothing that's ready to go out the door today, so I thought I'd follow the example of some of my compatriots and make a list. I expect some of these to be fairly idiosyncratic so consider with caution before adoption.
1. Learning how to cook pretty well. There's financial benefits to cooking your own meals, there's friendship benefits to cooking food for events, there's aesthetic benefits, health benefits. I think in addition to all of these cooking your own food can help put you more in tune with your body, since you can much more easily adjust and experiment with things you like more or less and things that make your body feel more or less good afterwards.
2. Eating meals to the extent that I want to at the times I want to. I've done everything from eating one meal a day at a regular time with a small snack earlier in the day to regular three meals a day to an irregular 1-3 meals a day at inconsistent times and they've all felt fine. The one main meal a day was good for losing a bit of weight, and in general, I'm able to feel really flexible in my ability to eat more or less for any given occasion. I'm able to go a fairly long time between eating without feeling bothered by hunger, and I'm fine with eating a lot of food in a short amount of time, which can be convenient. I believe this is something that can be trained, since this certainly wasn't always the case for me.
3. At least one time per day, I put conscious effort into thinking about the food that I'm eating. It either helps me be more thankful that I live in a world where I can easily access more than enough yummy food and/or helps enhance the aesthetic enjoyment.
4. Use spices! Use a lot of spices! Put 'em on and see what happens! Eventually you start learning about how different flavors mix but until then just keep putting spices on. (Do learn at least some basics about what goes with what beforehand)
5. I purchase very little in terms of snack/dessert-ish content. If there is food in the house, odds are that I am going to eat it before too long and having lots of snacks/dessert is bad for me. I'm not even sure about how it effects me at the nutrient level but they'll just generally be protein-scarce and I try to eat relatively high in protein. Also by avoiding the sort of hyper-palatable snack food that is really easy to eat, it's much more likely I'll naturally arrive at eating an amount of food that is appropriate for me. Sometimes I try making my own snacks and that's more fun.
There's a short list that manages to fulfill my word obligations. If you read this far, do you have any advice/recommendations on getting started with baking? I've done very little on that front so far but would like to go further.
