The world's number one product isn't a car, but yourself. Before you can successfully market yourself to others, you must first be one hundred percent sold on yourself. Without the sweat and spit of hard work, there can be no tears of success. When medicine matches the symptoms, a single sip is enough; when it doesn't, even a basketful is useless. There is always a gap between ideals and reality, but fortunately, that gap exists; otherwise, who would value ideals? To be fair, seeking profit is human nature. As long as one's actions comply with laws, morality, and ethics, pursuing wealth is perfectly legitimate and beyond reproach. Brothers are not mere fair-weather friends; they share the same blood, like melons on one vine or flowers on one plant. Friction in daily life is inevitable, but in moments of crisis, brothers unite—just like brothers who might bicker in the yard but stand together against an intruder. In real life, we have all seen or experienced it: when a lover must depart, one may lose their appetite and wither away in longing, desperately waiting for their return to end the heartache. Bees hum in thanks after gathering nectar, and leaves rustle in gratitude to the breeze. In life, everyone needs gratitude—to hold appreciation and give back to those who offer care and help. Just as lying is a tactic, telling the truth is also a way of navigating life. If one only competes with those less capable, one will find contentment. Giving others satisfaction brings one vitality. Let go when you must; only by learning to release can you avoid being burdened.
