A major goal of life should be mastering one’s own time. The ideal job is work that utilizes the leverage effect. In this work model, you can control your own time and be responsible for your own output and results. If you bring game-changing opportunities to a company by providing excellent solutions, you are guaranteed financial returns. Especially, if others don’t even know how you achieved it, they must continuously pay you, allowing you to keep providing that product or service. And the reason you can achieve this is because of your obsession, skills, or talent.
