EVERYTHING'S BEEN DONE BEFORE. THE SCENES CHANGE BUT THE BEHAVIORS AND OUTCOMES DON'T

The biggest lesson from the 100 billion people who are no longer alive is that they tried everything we’re trying today. They swung from optimism to pessimism at the worst times. They battled unsuccessfully against reversion to the mean. They learned that popular things seem safe because so many people are involved, but they’re most dangerous because they’re most competitive.

Same stuff that guides today, and will guide tomorrow.
