When the Addiction challenge was posed, I was in Houston. Standing in front of the masterpieces from around the world and thinking about the word, I feel uneasy. Suddenly, there are so many thoughts going through my brain. They are so diverse and complicated that I need time to find out what I am inextricably addicted to. Honestly, I don’t know what my addiction is till now because I am greedy. However, there is one thing that I must do every single day, namely, observing and recording nature. It has become my joys of life! Thank you, Sue, for the challenge topic. It is an opportunity for me to explore something that I have never thought of.
