You probably want some short, medium and long term goals. Short term like: try a new dish every week, listen a new podcast, watch a new film or series, read a new book, call and old friend once a week or message one every day.
Or trying to embed habits you have but aren’t quite there yet like - yoga three times a week instead of once, consistent skincare etc, sort your wardrobe into things you like and look good together.
Medium term could be - join a new group, try a new hobby, arrange to meet an old friend or a new friend every month, visit somewhere new but local, try a new cafe, etc
Long term - take a course or adult education class, travel somewhere new in the uk every year, learn a new language on Duolingo every year, visit a friend abroad, think about what causes you’re passionate about and how you could get more involved e.g. volunteering, raising money for charity etc.
I’d also encourage you to think about yourself and enjoying time on your own. How is your health? Is there anything you’d like to improve ?
