Why? Too often investors throw money around like scattering seed, saying to themselves, "I'll throw a little here and little there to see what happens." Instead, Buffett advocates a policy of finding the best and richest soil, planting substantial amount of seed in it, and protecting it. This policy may sound simple, and it is. It also can be life changing. Lou Simpson, one of the best investors in the world and head of GEICO's equity portfolio, once said that this particular Buffett strategy helped him enormously in his record of crushing the market over several decades.
