I haven't read the other responses yet, so I hope I don't repeat a bunch of stuff. If so, my apologies. Nature is full of endless entertainment and awe for me. I try to capture what catches my eye or takes my breath away with the camera every chance I get.
Kitchen time soothes (and nourishes) my soul, too. It's hard to get bored prepping and preserving garden goodies, or growing sprouts and/or microgreens indoors. Most especially when you don't eat what most others do, can't just order take-out or grab the "convenient" stuff any longer - for the health of it, and the level of creativity has to be kicked up a few notches as you go along.
I hear the following words in my head whenever I feel as if I've nothing to do - which were planted there by my late mother/grandmothers, as well as numerous bosses through the years - "If ya' got time to lean, ya' got time to clean." Be it dishes, laundry, sweeping, pulling dead stems/leaves off of houseplants, or whatever I see needs attention. At times, when I really feel like putting it off some more, I like to make a game of it and set a timer, or put on a favorite song/album, to see how much I can get done within that time frame.
Getting crafty with things that haven't yet outlived their excitement in my brain, or find a new one that doesn't require purchasing more crap to take up even more space. Creating something functional vs. just foofy inspires me even more at this stage of my life, but sometimes I just want to create, period.
Propagate a houseplant, or one of my herbs, or find a new "weed" that has a purpose/is edible, or try a new recipe with what I already have on hand or has already been clearly identified as being safe.
Grab a hula hoop and crank up some music, or just dance, or bounce on the mini-trampoline, or get on the aerobic exercise machine thingy, or on the fitness ball, or throw the thick mat on the floor and do some stretches - or - take all of the above outside and soak up some sun while having fun. If I look at it as exercise, or call it that, I'll likely avoid it. I call it purposeful daily movement. I set it up to be readily accessible indoors, except for the aerobic machine on the front porch, and the rest of it can easily be moved outdoors.
Write gratitude notes/letters, or emails, or make phone calls to local businesses/services/providers, or online businesses from afar, that have provided good customer service on any level. Most especially nowadays with stress levels being incredibly higher than usual. Folks need to hear thank you much more than they need to hear endless f yous and such.
Purge stuff. Then purge some more. Everything within our space costs us in the energy arena somehow, someway. We have to work around it, maintain it, move it, clean it, etc. etc. and just the thought of all of that can drain us before we even get started. Take a picture of it and save it on a thumb drive if it's truly meaningful, print photos for a coffee table book/photo album, or save the pics however you wish for the sentimental value of being able to look back on it whenever you wish to feel the love again. But if it isn't being used or bringing joy (other than the overwhelming desire to never let it go, even though it's taking up lots of space and energy to keep), let it move along.
Self-care opportunity. Soak in a hot bath with epsom salts - or just soak your feet. Trim and file your toe and finger nails. Wash your hair and dry it/style it. Wash your face and brush your teeth an extra time just because. Use your favorite oil/lotion to treat yourself to a leg, feet, shoulders, hands, etc. massage.
Turn your body into various makeshift instruments and make music just to be silly - like percussion, a horn section, beat boxing, etc. Find things in your immediate areas to make music with.
I'm sure I'm forgetting something. The most important thing is to try to make it pleasurable vs. feeling like you're creating a burden for yourself by engaging in the inner ass-kicking self-talk. My motto is to have fun whether "they" want me to or not. "They" is anyone who opposes my fun. lol
