I learned a couple of years ago that when we look up and look around, it automatically shifts our mood, and we feel lighter and happier. When we smile, we feel happier. Smiling is contagious. I have one friend who laughs constantly. People always eavesdrop on her, thinking her life is SO interesting.
Fun people are more interesting.
Paradise is a state of mind, heart, and soul. Get out and exercise, or do something to help you clear your head and think happier thoughts. One time, I was feeling down on a job. All of a sudden, the thought occurred to me that perhaps I was being hard on myself. That maybe, I'm better than I was telling myself.
