One of the major lessons I’ve tried to teach is that building your net worth comes down to two levers: Cash in and cash out. That’s it. That is the entirety of the game when you peer past the distractions and gaze into the heart of the mathematical reality. From a financial perspective, every action you take for your career or business ultimately only matters in so much as it someday serves to exert force on one of those levers so that more cash is flowing in than is flowing out, leaving a surplus. It sounds so simple but when you see things through the focus of this particular lens, you can more quickly identify the actions that are likely to have an outsized effect, both for good or bad, on net worth.
