Most of us tried various hobbies as kids, and then dropped them. Pick up a hobby you stopped as a kid and see if it still brings you the same joy it did then or maybe even if you hated it then and now love it.
Get the whole family involved and schedule summer play dates. Take time off of work and have a day of play with everyone.
The animals at a shelter desperately need some playtime, so stop by and spend 30 minutes walking a dog or two or petting some of the cats. The animals will appreciate the love and attention.
It’s not always easy, but schedule some playgroups for your kids. You’ll get a chance to hang out with some adults, and your kids will get to burn off some of their endless energy with their friends. Go to the zoo, hang by a pool, go to a theme park, go hiking, make a snowman, the opportunities are endless.
