Start with the little things you can change. Environmental noise, can you get headphones or earplugs? Social media making you feel down, curate your feed, change sites, or even take a breather. Change up a routine, try a different food, or a hobby. Whatever is in your power, a novel experience might be an idea. Decorate/personalize your space. Add some lights, tapestries, whatever you like. These are some ideas I’ve tried personally and enjoyed a few of.
