Shell mosaic---change another form to show beauty

Recently, I have a low spirit . This blue mood distract me from my work, my life. Maybe you also have such mode sometimes. In the influence of this mode, we don not want to do anything, even something that we like the best cannot get your interest.
I don’t want to be in this condition, but how to change? I tried many method, such as exercise, talking to friends and so on. However, these method did not work. Finally, I went to the beach. Walking on the beach, imaging I am a footloose fish, swimming in the sea, then I become more and more bright. The cloud that cover my heart disappear. Keep walking, I find some shells and I pick them up. How strong these shells are! 

Experiencing erosion of marine, the exposure of the sun, they still show their great vitality. Inspired by them, I felt that life is full of hope and my future is promising. The sadness vanished all of a sudden. I picked up a few shells to home and hope they can remind me to be a positive person. 
After go home, I fell in love with shells. I hope to live in a shell house, but it seems to be impossible. However, I can live in a house with some shell decoration like this:

I will achieve my dream-------live in a mother of pearl house.
