The easiest way? Become a tourist in your own town! Do an internet search for destinations in your own town and go exploring! Live by the sea...hit the beach. Live in a big city...head downtown. Frequently, museums offer free admission on Sundays.
Head to your local library. Check out a new book, a movie, or research a new hobby. All free!
Grab a leash! Perfect exercise for both you and your dog and a great opportunity to meet or visit with your neighbors.
Head outside with your camera or phone. Capture the beauty of the world around you.
Take some quiet time. Read, color, craft...even nap. Refresh your soul.
Above all else...enjoy yourself! The old adage is true. The best things in life are free!
