People who are naturally loud do not possess this important skill. So, the next time you’re in a situation where you’re just dying to say something, pause, take a moment, and ask yourself if what you have to say will really help the situation. Will you be giving people information that they need, making people laugh, or offering words of comfort, or will you be saying something just to be heard? If you don’t think anyone will actually benefit from what you have to say, then keep it to yourself. One rule to follow when you’re starting off is to say one of every two things you’re thinking. As you work on being more quiet, then you can say one of every three things, or one of every four things. Don’t ever interrupt a person while he or she is talking unless you think what you have to say is crucial to the conversation. (Let’s face it. – When is that ever the case?) Not only is it rude to interrupt people, but it will disrupt the flow of the conversation and will make you appear  loudmouth. If you really have a comment to make or a question to ask, then make a note of it and wait until the other person is done talking to see if what you have to say is still relevant. You’d be surprised by how many of your questions will get answered anyway if you just let people talk. If you’re working on being more quiet, then chances are that you tend to talk on and on about yourself or the things that really interest you instead of letting other people share their ideas. So, the next time you’re having a conversation and it’s your turn to speak, ask people questions to gain insight about the topic you’re discussing and to learn more about them – from what their hobbies are to what they like to do for fun. You don’t have to make it sound like an interrogation or ask questions that make people uncomfortable. Keep things light, friendly, and polite and remember that conversation, in large part, is more about saying that you care about and are interested in the other person's thoughts, feelings, and point of view and less about...

How would you rephrase that briefly using Indonesian?
Berpikirlah dahulu sebelum bicara. Jangan menyela. Ajukan pertanyaan alih-alih berbicara tentang diri Anda sendiri. Hitung mundur dari angka sepuluh sebelum Anda mengucapkan sesuatu. Dengarkan secara saksama. Berhentilah mengeluh. Fokuskan perhatian Anda pada napas. Luangkan waktu untuk mencerna apa yang Anda dengar.
