Cultivated individuals are always cautious about the people they associate with. Some opportunities, once missed, can never be caught again, just as some mistakes, once made, can never be undone. However, every choice we make is a solemn decision among many possibilities. Therefore, by saving an opportunity, we are giving ourselves more chances for future choices. No one hands you opportunities, and opportunities do not simply arrive on their own; you must actively pursue them. One habit of successful people is: grasp opportunities when they arise, and create them when they do not. Napoleon Hill said, 'The only luck a person can rely on is the opportunity they create themselves'—this requires perseverance, and a fixed goal is the starting point of success. Perhaps a century ago, people could still tackle multiple pursuits with ease. With the development of modern society, every profession requires full dedication. Unless you possess exceptional talent, the most likely outcome of attempting to manage multiple fronts is failure on both. Life is like a dream, and time is relentless. To look at life with detachment is to understand impermanence; to see through career is to understand choice; to perceive love is to understand reunion and parting. Being beautiful is an advantage, but living beautifully is a skill. Once a person has a dream of flying, there is no reason not to stand up, even if they are currently crawling. Love yourself, rely on yourself, and be yourself. The Three Capacities of Life: Human life can be measured by three 'capacities': first is courage, the boldness to face the unknown; second is strength, the vigor of one's efforts; and third is capacity, which is proportional to knowledge—the more you learn, the wider your breadth of mind becomes. One should remain gentle and avoid excessive anger, as anger can often bring great misfortune to those who are quick to temper. For those who do not know how to use opportunities, opportunities are like waves rushing into the vast ocean or eggs that never hatch. Life is inherently imperfect, and everyone has flaws. Yet, without these imperfections, we would be unable to measure perfection. In a way, flaws are indeed a form of perfection themselves.
