Eat smaller portions - I only eat 2 meals a day and yet I'm putting on weight - can only be the portion size! Also, reduce carbs.
Quit drinking - useless calories, and it doesn't help me get a good night's sleep
Get a bit more exercise - nothing too strenuous, just more regular and often
Do some actual, physical art, as opposed to digital stuff - it won't be pretty to start with, but I'm sure I'll improve over time
No screens in bed - I want to get back to reading real, paper books
Eat more fish - I love it, DH doesn't, but I can do something different (like a burger) for him, without too much trouble. He doesn't cook - which is a blessing.
Continue to not buy clothes - I have loads that I rarely wear - I'm mostly in black T-shirts and leggings, which is fine by me. I don't need new ones.
The only other thing is to be very frugal in Jan and Feb, and eat our way through the contents of the chest freezer - which are many, and various. Might even last until March, with just weekly shopping for perishables like veg, milk etc.
Work on making more local friendships - I was away for a couple of years looking after my Dad (RIP) and kind of lost touch with local people. Since coming back, and then Covid, I've not renewed my old contacts, nor made new ones. This will change.
So, it's quite a list - but I think it's all positive. I don't feel bad about my current life, I'm just looking for ways to make it better.
