Try some income producing real estate. It can be done hands off via syndications or hands on via direct ownership. A nice in between option is NNN commercial buildings and/or hiring a property manager. Each approach has its pros and cons.

​​​​​​Over the last 14 years, real estate has crushed my index funds. In 2007 it was 80/20 in favor of funds. Now it's 80/20 the other way. To be fair, most of the real estate was actively managed, so the gains include sweat equity. Balancing that out is the DC contribution into index funds. The RE was only funded out of pocket for the first 5 years, the last nine have been only reinvestment. The index funds have been 415 maxed every year.
