Daniel Kahneman's research on the 'experiencing self' versus the 'remembering self' reveals something counterintuitive about productivity: the brain doesn't store time, it stores peaks and endings. This means a focused 90-minute session that ends on a satisfying small win will be remembered — and repeated — more readily than a grueling 4-hour marathon, even if the marathon produced more output. For brain health and sustainable work rhythms, this suggests designing your Sundays not around maximum effort, but around deliberate closure — ending tasks at moments of mild success rather than exhaustion. Kahneman didn't intend this as productivity advice, but the implication is clear: architect your endings, and your future self will thank the editor, not the author.

Think of a recurring task you tend to avoid — is it possible you've trained yourself to associate it with how it *ended* last time, rather than how it actually went overall?
