I learned to go into business only with people whom I like, trust, and admire. - Warren Buffett

Since I entered the business world, conglomerates have enjoyed several periods of extreme popularity, the silliest of which occurred in the late 1960s. The drill for conglomerate CEOs then was simple: By personality, promotion or dubious accounting — and often by all three — these managers drove a fledgling conglomerate’s stock to, say, 20 times earnings and then issued shares as fast as possible to acquire another business selling at ten-or-so times earnings. They immediately applied “pooling” accounting to the acquisition, which — with not a dime’s worth of change in the underlying businesses — automatically increased per-share earnings, and used the rise as proof of managerial genius. They next explained to investors that this sort of talent justified the maintenance, or even the enhancement, of the acquirer’s p/e multiple. And, finally, they promised to endlessly repeat this procedure and thereby create ever-increasing per-share earnings.

Our managers are totally in charge of their personal schedules. Second, we give each a simple mission: Just run your business as if: (1) you own 100% of it; (2) it is the only asset in the world that you and your family have or will ever have; and (3) you can't sell or merge it for at least a century.

No matter how great the talent or efforts, some things just take time. You can't produce a baby in one month by getting nine women pregnant.
