My friend said, 'I finally started investing in index funds.' I said, 'That's smart! How much are you putting in?' He said, 'Fifty dollars a month.' I said, 'Where are you putting it?' He said, 'I have a folder on my phone called Investing. In the folder, there's a screenshot of a website. The website has a graph. The graph goes up and down. I look at it every day.'
