Everyone will have many unpleasant things in his life, but we just need to remember the following words, so that our life will be happy every day! Be grateful to the person who abandoned you, because he taught you independence. Be grateful to the person who hurts you, because he has honed your mind. Be grateful to the person who tripped you, because he strengthened your legs. Be grateful to the person who cheated you, because he improved your wisdom. Be grateful to those who despise you, because they awaken your self-esteem. I am grateful for failure, because it makes me a storyteller. Grateful for success, because it makes my life full of wonderful and beautiful; Thanks for applause and encouragement, because it gives me more energy and courage! At the same time, I am grateful for criticism and challenge, because it reminds me to know and understand. Be grateful for everything, learn to be grateful, and thank all the people who let us grow up!
