You have to be able to communicate in life and probably schools underemphasize that. If you can't talk to people or write, you're giving up your potential.
None of this means, however, that a business or stock is an intelligent purchase simply because it is unpopular; a contrarian approach is just as foolish as a follow-the-crowd strategy. What's required is thinking rather than polling. Unfortunately, Bertrand Russell's observation about life in general applies with unusual force in the financial world: "Most men would rather die than think. Many do."
If the world couldn't see your results, would you rather be thought of as the world's greatest investor but in reality have the world's worst record? Or be thought of as the world's worst investor when you were actually the best?
One observer commenting on security analysts over forty stated: "They know too many things that are no longer true." As long as I am "on stage", publishing a regular record and assuming responsibility for management of what amounts to virtually 100% of the net worth of many partners, I will never be able to put sustained effort into any non-BPL activity. If I am going to participate publicly. I can't help being competitive. I know I don't want to be totally occupied with out-pacing an investment rabbit all my life. The only way to slow down is to stop.
Risk comes from not knowing what you are doing so wide diversification is only required when investors are ignorant. You only have to do a very few things in your life so long as you don't do too many things wrong.
Managers thinking about accounting issues should never forget one of Abraham Lincoln's favorite riddles: How many legs does a dog have, if you call a tail a leg? The answer: Four, because calling a tail a leg doesn't make it a leg.
The approach and strategies are very similar in that you gather all the information you can and then keep adding to that base of information as things develop. You do whatever the probabilities indicated based on the knowledge that you have at that time, but you are always willing to modify your behaviour or your approach as you get new information. In bridge, you behave in a way that gets the best from your partner. And in business, you behave in the way that gets the best from your managers and your employees.
If you've got a good enough business, if you have a monopoly newspaper, if you have a network television station - I'm talking of the past - you know, your idiot nephew could run it. And if you've got a really good business, it doesn't make any difference.
If you don’t feel comfortable making a rough estimate of the asset’s future earnings, just forget it and move on. No one has the ability to evaluate every investment possibility. But omniscience isn’t necessary; you only need to understand the actions you undertake.
