Episode 7: How the Peak-End Rule Shapes Your Happiness

Do you remember how something felt, or just how it ended?
This week on Redefining Happiness, we explore the Peak-End Rule, a concept from psychologist Daniel Kahneman that shows how our memories of experiences are shaped by two key moments: the emotional high point and the ending. The rest often fades away.

You’ll learn why these two moments matter so much, how they influence your decisions and life story, and how businesses are already using this psychological insight to shape your loyalty and perception. More importantly, you’ll discover how you can apply this same principle to create richer, more meaningful memories in your everyday life.

Whether it’s your daily routine or a once-in-a-lifetime trip, you’ll leave this episode with tools to design more intentional, joy-filled moments, both while you’re living them and long after they’ve passed.

What You’ll Learn:

• Why your memory doesn’t capture the full experience, and what it remembers instead

• How the Peak-End Rule is already used in hospitality, entertainment, and retail to shape your perception

• Simple ways to design better moments in your day, from errands to workouts to relationships

• Why you don’t need to control everything, just the peaks and the endings

This Week’s Happiness Challenge: The Meaningful Moments Challenge

This week make I want you to make a point of intentionally creating a positive ending to some part of your day. Work, workout, errands, anything. It does not have to be big. It could be singing along to a favorite song, a few minutes of gratitude, or even treating yourself to a brownie.

At the end of your day, reflect: How did that ending shape your memory of the day?

Lastly. At the end of the week, notice how your week felt when your tasks start feeling more fun.
