"自分の欲望や食欲を制御できる人は最も困難で高貴な仕事を遂行する能力がある。"

Simplified Meaning:

When a person can manage their cravings and urges, they can handle challenging and important tasks. Think about a student who really wants to play video games but chooses to study for their exams instead. This student is showing self-control by focusing on something that will benefit their future rather than giving in to immediate pleasure. In history, many successful leaders and thinkers practiced self-discipline. For example, Mahatma Gandhi fasted regularly and lived simply to stay focused on his goal of achieving independence for India. By controlling his wants, he could dedicate himself to a greater cause. Anyone can use this advice by practicing self-control in their own life. If you save money instead of spending it on things you don't need, you can achieve bigger financial goals like buying a house or starting a business. This approach helps you stay committed to what truly matters, leading to greater achievements.
