Studying history and watching too many people's endings make me feel chilling, feel that life is boring, and my ambition to struggle is gone.
History is history. There are too many failures, but there are also many successes. There is a lot of negative energy and courage. Better look on the bright side. Life is not always interesting, but learn to enjoy and taste life, and then pursue your own ideals and strive hard, instead of sitting here and talking about your own ambitions. How can other people's failures affect you?
