Derek Sivers in The past is not true:
Aim a laser pointer at the moon, then move your hand the tiniest bit, and it’ll move a thousand miles at the other end. The tiniest misunderstanding long ago, amplified through time, leads to piles of misunderstandings in the present. We think of the past like it’s a physical fact - like it’s real. But the past is what we call our memory and stories about it. Imperfect memories, and stories built on one interpretation of incomplete information. That’s “the past”.
