Have fun in everything
Most of us take life too seriously. We focus on our pains and problems and the possibility of pains and problems in the future. We dwell on the negative and obliterate the sunshine beaming on us from all around. Save serious for the really big things and allow yourself to have fun, to explore your vision, to make mistakes and learn from them, to see the beauty in the moment.
Be bold, and have fun with your writing.
