Trust in time rather than timing.

Never buy anything from someone who is out of breath.

Index funds are... tax friendly, allowing investors to defer the realization of capital gains or avoid them completely if the shares are later bequeathed. To the extent that the long-run uptrend in stock prices continues, switching from security to security involves realizing capital gains that are subject to tax. Taxes are a crucially important financial consideration because the earlier realization of capital gains will substantially reduce net returns.

Stupidity well packaged can sound like wisdom.

Experience conclusively shows that index-fund buyers are likely to obtain results exceeding those of the typical fund manager, whose large advisory fees and substantial portfolio turnover tend to reduce investment yields. Many people will find the guarantee of playing the stock-market game at par every round a very attractive one. The index fund is a sensible, serviceable method for obtaining the market's rate of return with absolutely no effort and minimal expense.

A blindfolded monkey throwing darts at a newspaper's financial pages could select a portfolio that would do just as well as one carefully selected by experts.

Trust in time rather than timing.
