Avoid organizing investment team into silos.

Warren 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.

Be focused on process and not outcome

I find value investing to be a stimulating, intellectually challenging, ever changing, and financially rewarding discipline

In reality, no one knows what the market will do; trying to predict it is a waste of time, and investing based upon that prediction is a speculative undertaking.

Complexity - limits competition.

We don't deal in absolutes. We deal in probabilities.
