Some say that silence is golden. Indeed, in many moments, silence is far more preferable to constant chatter, at the very least it does not annoy people. However, excessive silence is not necessarily a good thing. Once you lose the desire to speak, it means you have also lost many opportunities to share joy and bring happiness to others. I used to be a very emotional person, but now I have become calm, with no joy, sorrow, or anger.

In every conversation with others, if you are the listener, learn to listen, as listening is often better than comforting.

与人的每一次交流，若作为倾听者，要懂得聆听，因为倾听往往胜过安慰；遭遇的每一挫折，若源于错误，需及时反思，因为反思胜于单纯的对比；攀登的每一座高山，要努力跨越，有所得，不辜负坚持与汗水。人生若能受得了磨难，生活便能吃得下苦头，受得了挫折，忍得住寂寞。唯有如此，回首往事时，才无悔恨。
