I feel like not many of us really go outside and sit in the sun or walk around your town or anything. We should do that because you can't always just sit inside your room, cramped up and that is definitely not the way to spend your summer, so take a road trip with some friends or go to the beach, and even the little things can be so good for you and take the stress off your shoulders, for example walking your dog to the park or playing with your pet.
Just remember that you can always go outside and do something interesting out there instead of being inside your room because there is always something more healthier for your body and will make you feel great. Think about it! :)
