That's what I've recently discovered. Dumping everything into VTSAX is the best thing you can do to your investments, but then... where's the excitement? So I've allowed myself a "fun money" brokerage account that I initially deposited $5k into, and just play with options trading. I've already paid myself back the initial investment, so any profit/loss from now on is irrelevant. This way I can still geek out over investing, but not gamble my life savings.
