Many people think that doing business requires being "kind," but the reality is that successful businesspeople often have a ruthless mindset—not because it's evil, but because it's a necessary foundation for survival. Without a tough mentality, your principles won't hold firm. Being ruthless in business means zero tolerance for losses, decisive action to cut losses, and decisively keeping your distance from ineffective relationships. Soft-hearted people cannot succeed in business because they're constantly compromising, hesitating, and worrying about others' feelings. True businesspeople understand that rules override sentimentality, interests supersede emotions, and results matter more than feelings. A ruthless approach to business isn't evil—it's vision, it's wisdom, and it's the highest form of self-discipline for mature adults.
