“Don’t ask the barber whether you need a haircut.”

“It takes character to sit with all that cash and to do nothing. I didn't get top where I am by going after mediocre opportunities.”

“We both insist on a lot of time being available almost every day to just sit and think. That is very uncommon in American business. We read and think. So Warren and I do more reading and thinking and less doing than most people in business.”

“No business can continue to shrink. That can only go on for so long before irrelevancy sets in.”

“We will make bold rather than timid investment decisions where we see a sufficient probability of gaining market leadership advantages.”
