Accept what cannot be changed and change what can be changed. When you achieve achievements and honours, don't be complacent and get carried away; when you encounter failures and setbacks, you must muster courage and dare to face them, always be calm when you are proud, calm when you are frustrated, and always maintain full enthusiasm for work. As a philosopher said, you can't change the environment, but you can change yourself; you can't change the facts, but you can change your attitude; you can't change the past, but you can change the present.
