Be indifferent if you lose your short term clients, remember they are your own worst enemy

Successful investors must temper the arrogance of taking a stand with a large dose of humility, accepting that despite their efforts and care, they may in fact be wrong.

A simple rule applies: if you don't quickly comprehend what a company is doing, then management probably doesn't either.

Short-term performance envy causes many of the shortcomings that lock most investors into a perpetual cycle of underachievement. Watch your competitors not out of jealousy but out of respect and focus your efforts not on replicating others' portfolios but on looking for opportunities where they are not. The only way for investors to significantly outperform is to periodically stand far apart from the crowd, something few are willing, or able, to do.

To value investors the concept of indexing is at best silly and at worst quite hazardous. Warren Buffett has observed that "in any sort of a contest - financial, mental or physical - it's an enormous advantage to have opponents who have been taught that it's useless to even try." I believe that over time value investors will outperform the market and that choosing to match it is both lazy and shortsighted.

Value investors have to be patient and disciplined, but what I really think is you need not to be greedy. If you're greedy and you leverage, you blow up. Almost every financial blow up is because of leverage.

Investment success cannot be captured in a mathematical equation or a computer program.
