Willpower is the power that determines success or failure. This sentence has been with me for three years in high school. I don't know if you have read the article "Why I was admitted to Peking University", which tells the story of a girl named He who finally got admitted to Peking University through her own efforts. When talking about his efforts and almost collapse, she saw a banner hanging on the wall of the opposite building: the power of will is the power that determines success or failure. When I first saw this sentence, I was shocked all over. I think. In fact, it takes courage to believe this sentence. We are often unwilling to work hard, not because of anything else, but because we are afraid that our efforts will be ineffective, which will eventually make many efforts in vain. Those who choose to believe this sentence will have to bear the situation that the pay and return may not be equal. This is almost a belief-based answer, yes, the power of will is the moment that determines success or failure. I firmly believe that my efforts will pay off, as long as I devote all my energy.
