使用了if引导的条件状语从句并配合反问句式来加强语气。
Being petty is a negative way of living. Some people not only obsess over financial rewards but also fret over others' attitudes, even holding grudges over slights from years ago. I once encountered such a person. During a middle school reunion, after thirty years of separation, everyone should have been filled with emotion. Instead, the conversation was strained; before the meal was even halfway through, the person began bringing up old grievances, complaining about how someone had offended them years ago. It is no wonder such a person struggles in life; If one is constantly dwelling on the past, how can they ever achieve a broader perspective?
斤斤计较是一种消极的人生态度。有些人不仅计较报酬多少，还计较他人的态度，甚至对于多年以前的过节也耿耿于怀。我也曾遇到过这样的人。在一次初中同学聚会上，三十多年未见，大家本该感慨万分，谁知对方却言语不投机，饭局还没过半，就开始翻旧账，抱怨当年谁曾得罪过他。这种心态难怪会让人生活不顺，整天沉溺于陈年旧事，又怎能拥有开阔的心胸呢？
"Learn the art of living by always keeping the bigger picture in mind."
"Vision shapes perspective, and perspective shapes destiny."
"The former determines the ease of your life, while the latter determines how far you can go."
"Life is a grand realm; one need not insist on local perfection."
