Explore a city by going on a walking tour. You can learn a lot about the local history, and going at a slower pace allows you to take in more. There are endless tour options available, everything from historical to ghost tours. A little extra exercise is nice too.
Take advantage of the parks system in your city. Walk around the garden paths. Have a picnic. Lay and read in the grass. Photograph the flowers. Run, walk, or bike on the fitness paths. Bring your kids to the playgrounds. Attend free concerts or movie nights. Spend time at the park.
Get a library card for your local library. Find out what they offer. Many library networks offer more than just books to lend. You can often get media (movies, music, ebooks, etc), museum passes, internet access, access to community events, etc. Take advantage of this free resource.
Practice hanging and moving around on the monkey bars like a kid. Play! It has probably been years since you climbed up and hung by your arms, but try it. If you haven’t kept your weight down, and arm strength up, it will be hard. But if you look at it with all of the excitement of a child, you will have fun as you practice and get better.
On a nice day, lay in the grass. Take a nap. Have a picnic. Read a book. Enjoy the warmth of the sun. Enjoy the softness of the grass.
Say, “Cheers!” when you are toasting with someone. Look them in the eyes. Smile!
Listen. Listen to nature. Listen to laughter. Sit back and listen to the white noise. Listen to children. Listen to your heart. Listen.
