When it comes to portfolios, my personal advice is for anyone who can, put money into forestry or farmland. Long term, you would probably never come near their returns in the stock market. In the world that I see, land is golden.

Investors should remember that their scorecard is not computed using Olympic-diving methods: Degree-of-difficulty doesn't count. If you are right about a business whose value is largely dependent on a single key factor that is both easy to understand and enduring, the payoff is the same as if you had correctly analyzed an investment alternative characterized by many constantly shifting and complex variables.

To be an investor you must be a believer in a better tomorrow.

If you are predisposed to be patient, disciplined and psychologically appreciate the idea of buying bargains, then you're likely to be good at it. If you have a need for action, if you want to be involved in the new and exciting technological breakthroughs of our time, that's great, but you're not a value investor, and you shouldn't be one.

It seems to me - particularly for these retirement-plan investors, the vast majority of whom are not particularly financially sophisticated - by far the best way is to invest in index funds.

You're looking for a mispriced gamble. That's what investing is. And you have to know enough to know whether the gamble is mispriced. That's value investing.
