"是傲慢使天使变成了魔鬼，是谦逊使人成为天使。"

Simplified Meaning:

Pride can be very harmful; it can make good people turn bad, just like how it was said that angels became devils because of their pride. For example, if someone at work gets a promotion and starts thinking they are better than everyone else, they might begin treating their coworkers poorly. This kind of attitude can create problems and lead to losing respect and friends. On the other hand, humility, which means being modest and respectful, can make people much better. Think of a leader who always listens to others, shares credit, and values everyone's contributions. This kind of behavior makes them admired and respected, almost like an angel because they bring out the best in everyone around them. To apply this to your life, try to stay humble and treat others kindly, no matter how successful you become. Remember that everyone has something valuable to offer, and recognizing this can create a more positive environment for everyone.
