The cartoon aims at informing us of the significance of an optimistic mindset. Definitely, no once can deny the importance of it. An optimistic mindset can help us achieve our objectives more smoothly and realize our dreams more rapidly. By being optimistic. we can face challenges and surmount hardships with confidence，keep sober and figure out effective measures even in desperate situations. To further illustrate the importance of being optimistic, I would like to take Beethoven as a case in point: how could he, a great German music composer who became deaf at his forties, compose so many enduring and classic symphonies without optimism?

Accordingly, at no time should we overlook the power of optimism. once coming across frustrations and intending to give up, we should remind ourselves that it is optimism that will finally lead us to turn the corner. “the optimistic sees the rose， and the pessimistic sees the thorn.” A philosopher once said.
