It was the 1960s. At the time the stock market was booming and everyone was talking about it, especially the people I caddied for. So I started to invest. The first stock I bought was a company called Northeast Airlines, and the only reason I bought it was that it was the only company I had heard of that was trading for less than $5 per share, so I could buy more shares, which I figured was a good thing. It went up a lot. It was about to go broke but another company acquired it, so it tripled. I made money because I was lucky, though I didn’t see it that way then. I figured that this game was easy. After all, with thousands of companies listed in the newspaper, how difficult could it be to find at least one that would go up? By comparison to my other jobs, this way of making money seemed much more fun, a lot easier, and much more lucrative. Of course, it didn’t take me long to lose money in the markets and learn about how difficult it is to be right and the costs of being wrong.
