I found a new word sounds nice today. Credo.
One of My credo in my life is a famous phrase that is said by Shinsaku Takasugi, Japanese Samurai who lived and played an active and important role for the Meiji Restorration.
"The world that is uninterested, I shall interesting."
"Let us make an uninteresting world interesting."
Also it can be translated to
"Do something interesting in this boring world!!"
