I do not envy or resent couples who are always glued together. I have neither the time, the interest, nor the energy to cross time zones to argue, throw tantrums, or break up over trivial matters. What I can do is simply wrap up my coat when the wind blows, keep reading, actively participate in various activities, memorize many new words, maintain a healthy sleep schedule, and work hard on my fitness. I hope that no matter which day it is in the future, I will have the qualification to stand by your side with an unchallengeable and confident posture.
Being belittled or despised by others is actually a good thing. If you are unwilling to accept such treatment, you must put in a hundred times the effort.

Being poor is not scary; what is scary is relying on others for relief indefinitely. Loneliness is not scary; what is scary is being lonely forever.

被人贬低和蔑视，其实也是一件好事。如果不甘心于此，就要付出百倍的努力，用数倍于他人的成果自立于众人之前，让狂妄者心服口服。这是从贬低中获益的要旨，关键在于自强不息，奋发向前。
没钱并不可怕，可怕的是长期依赖他人的救济；孤单并不可怕，可怕的是陷入长久的孤独；失业并不可怕，可怕的是始终不采取行动寻找工作；生病并不可怕，可怕的是病入膏肓、一病不起；失败并不可怕，可怕的是彻底一败涂地。
