Be indifferent if you lose your short term clients, remember they are your own worst enemy
Seth KlarmanYou need to balance arrogance and humilitywhen you buy anything, it's an arrogant act. You are saying the markets are gyrating and somebody wants to sell this to me and I know more than everybody else so I am going to stand here and buy it. I am going to pay an 1/8th more than the next guy wants to pay and buy it. That's arrogant. And you need the humility to say 'but I might be wrong.' And you have to do that on everything
Seth KlarmanValue investing requires a great deal of hard work, unusually strict discipline, and a long-term investment horizon. Few are willing and able to devote sufficient time and effort to become value investors, and only a fraction of those have the proper mind-set to succeed.
Seth KlarmanSelling, in particular, can be a challenge; many investors are tempted to become more optimistic when a security is performing well. This temptation must be resisted; tax considerations aside, when a security reaches full valuation, there is no longer a reason to own it.
Seth KlarmanWarren Buffett likes to say that the first rule of investing is "Don't lose money," and the second rule is, "Never forget the first rule." I too believe that avoiding loss should be the primary goal of every investor. This does not mean that investors should never incur the risk of any loss at all. Rather "don't lose money" means that over several years an investment portfolio should not be exposed to appreciable loss of principal.
