1. Go for a "walk" or drive, or whatever, once a week with the main purpose of taking photos. (Or bring your camera along on something you're already doing, or walk to your back yard... and it doesn't have to be exactly once a week, but roughly once a week.)
2. Take a photo, or two, or 200. Post your favorite, or two, or 200. Edit them if you wish.
3. That's it.
