I got a 7k bonus 20 years ago in the military. I seriously considered investing it in the Vangard total stock market index fund. In '04 it was trading at $54 per share, today $282. Had I invested that $7,000 I would have $365,555 today. Instead I “invested” it at the strip club because I was a young dumb E-3 in Pensacola and New Orleans was only a weekend pass away. Long story short, index funds are the way to go.
