Given advice “buy term insurance and invest the rest”, how should one “invest the rest”?
The simplest way is to invest in a few ETFs, depending on your tolerance for risk; assuming you're very short-term risk tolerant you can invest almost all in a stock ETF like VOO or VTI.  Stock market ETFs return close to 10% (unadjusted) over long periods of time, which will out-earn almost any other option and are very easy for a non-finance person to invest in (You don't trade actively - you leave the money there for years).  If you want to hedge some of your risk, you can also invest in Bond funds, which tend to move up in stock market downturns - but if you're looking for the long term, you don't need to put much there. Otherwise, try to make sure you take advantage of tax breaks when you can - IRAs, 401Ks, etc.; most of those will have ETFs (whether Vanguard or similar) available to invest in.  Look for funds that have low expense ratios and are fairly diversified (ie, don't just invest in one small sector of the economy); as long as the economy continues to grow, the ETFs will grow.
