Passive Management
  
Of money. Think: index funds. ETFs. A "buy one stock and hold it forever" strategy.
That's it. Passive. You don't care what the market does on any given day or week or month. You think in years. Decades. You just let the money get put to work, and watch it compound at the 8 or 9 percent rate at which it has historically compounded over the last century and change. And you kiss the ground of America, so happy you can invest like this and let the system work for you, instead of things being the other way around.
