Financially, the right decision is the one with the greater expected value, while accounting for the marginal utility of money. Your understanding of the stock market is fundamentally wrong, owning a stock is owning a piece of a company, a company where people spend most of their lives trying to make a profit, for you, the shareholder. It's a gamble to put all your money on one company, because some companies fail. Buying shares in a large number of companies is the best long term expected value you'll find.
