Victor Frankl said our last freedom is to choose our attitude. By watching our thoughts and feelings with deep awareness, we can discover how our feelings affect our thoughts and how our thoughts influence our feelings.
We can consciously create a happy outlook by thinking happy thoughts on purpose. Happier, we can create more joy in our lives. Try getting still for a few moments and pay attention to your thoughts and feelings. Then think about someone or something that makes you very happy. Notice again how you're feeling. Repeat as needed to cultivate a cheerful attitude, and see how that inspires your creativity.
