If you stripped Bill Gates of his assets and dumped him on the street…he’d be back to living a comfortable life with plenty of income in about a week. Why? Bill Gates has tons of human capital.
Wikipedia defines human capital as “The stock of competencies, knowledge, social and personality attributes, including creativity, embodied in the ability to perform labor so as to produce economic value.”
If Bill Gates suddenly became homeless he could walk into the headquarters of any major company on the planet, offer his services as a consultant and start making 6+ figures a year. Focusing on building your human capital is a lot more productive than worrying about “job security.”
