Watch old black and white movies and you'll appreciate the quality of their acting, the values they held, etc. Lay on the ground and watch clouds. Look at great pieces of art and appreciate it in ways you didn't know you could. Grab you camera and take pictures of landscapes or plants. You'll see and find great spots to frame and capture an image. Listening to old timey music from the 50s or older. It can take you back to a time when people were just happy. This works for most music from the 80s or older, but almost anything before Rock really does the trick. Feel those feelings, and think the thoughts that come from the feelings, and you'll realize that the natural state of people requires most people (these days) to get high to achieve what should be our default.
