Our future rates of gain will fall far short of those achieved in the past. Berkshire's capital base is now simply too large to allow us to earn truly outsized returns. If you believe otherwise, you should consider a career in sales but avoid one in mathematics.
If you understood a business perfectly and the future of the business, you would need very little in the way of a margin of safety.

If you're driving a truck across a bridge that says it holds 10,000 pounds and you've got a 9,800 pound vehicle, if the bridge is 6 inches above the crevice it covers, you may feel okay, but if it's over the Grand Canyon, you may feel you want a little larger margin of safety.

We've seen what can be accomplished when we use 50% of our human capacity. If you visualize what 100% can do, you'll join me as an unbridled optimist about America's future.
