If you want to stop being selfish, then you have to learn to listen to other people. And that means you should really listen, not just nod, and say "Uh huh," until it's your turn to speak. Listening means absorbing what people say, remembering what people say, and understanding the problems of your friends, significant others, and coworkers. It can also help if you ask open-ended questions that give your conversation partner a chance to express him or herself.  Don't interrupt. After your friend talks, give a thoughtful response by referencing points made in the conversation to show that you really paid attention. If your friend has a problem, don't instantly compare it to your own problem, which you claim is "way worse." Take every problem on its own terms and give relevant advice when you can without making it all about you. You can say something like, "I was in a similar situation, and this is what helped me. Do you think it might work for you?" This small and simple gesture could make a big difference in your friendship. One key aspect of being a good friend is being supportive, which includes supporting your friend's activities from time to time. The next time you and your friend hang out, let her pick the movie, the dinner place, the happy hour bar, or the activity that you'll do together.   Once you get in the habit of doing this, you may find that you get pleasure out of making the people you care about happy. You can also take turns. She can pick what you'll do one week and you can pick what you do the next. Go to the store, shop for the things that you know your friend will love, and then spend at least an hour cooking a delicious meal and setting the table. Preparing a meal for your friend takes time, money, and effort, and you'll see how good it feels to do something nice for another person.  This is an especially nice gesture if your friend is tired, broke, or in need of some comfort.  Don't make your friend bring over anything except something to drink. You'll be doing all the work that night....

How would you rephrase that briefly using Chinese?
