Would you like to continue working with children through the summer? Maybe you could find a summer camp, youth group, or somewhere like the Y that you could work or volunteer during the summer months.
If you enjoy getting a break from the kids, then maybe the summer could be a chance to do more of the fun things that get put to the side during the school year. You could make a list of museums, zoos, parks, and restaurants that you'd like to try in your own city, or in surrounding cities. Then you could try visiting a couple a week.
Do you enjoy flowers? You could start a garden in your yard, or make window boxes if you are in an apartment. Taking care of my garden takes as much of my time as I want it to, and feels very peaceful.
I hope you get to enjoy your summer.
