Final answer:
The authors recommend avoiding the strategy of trying to pick stocks that will gain a great deal in the future.
Step-by-step explanation:
The authors recommend the investing mantra "get rich slowly." They recommend avoiding the strategy of trying to pick stocks that will gain a great deal in the future. The reason for this is that the majority of financial investors do not outguess the market, and attempting to pick stocks that will outperform the market average is a risky and unlikely way to become rich. Many other investors are also trying to do the same thing, so even if you identify a company with high future profits, the stock price may already be high.
