I made a collage of encouraging quotes and photos of places I have been active in the past - kayaking and backpacking. It also includes photos of places I want to hike, canoe, and wildlife I want to see. Currently, there are 8 quotes and 25 photos taped to my closet doors. I have added pictures to my profile to give you an idea of the layout.
I made the photos different sizes and colors. It helps to have this as a main focal point in my bedroom. If I try to procrastinate working out or eating healthy, I have this huge reminder of where I want to be.
