The Fulfillment Curve

Quantify your life experiences as points on a curve to visualize and maximize lifetime fulfillment.

Problem it solves

The Fulfillment Curve addresses the core challenge described in its foundation: The Fulfillment Curve is a visualization framework that treats each year of your life as generating a measurable number of 'experience points' based o.

Best for

Analytically minded people who respond well to quantification and visualization. Engineers, data-oriented thinkers, and anyone who makes better decisions when they can see the numbers.

Not ideal for

People who find quantifying emotions or experiences reductive or stressful.

Overview

Why this framework exists

The Fulfillment Curve is a visualization framework that treats each year of your life as generating a measurable number of 'experience points' based on the quality and quantity of positive experiences you had. When you plot these points as bars on a chart, the resulting curve represents your lifetime fulfillment. Your goal is to maximize the total area under this curve.

This quantitative lens transforms abstract questions about 'living a good life' into concrete optimization problems. If last year scored 5,090 experience points and this year only 3,200, what changed? Did you trade too much time for money? Did declining health limit your activities? Are you deferring experiences that would have scored highly? The framework makes it possible to compare different life strategies and identify which decisions increase or decrease your total fulfillment.

The curve also reveals the impact of memory dividends: because experiences continue to generate small experience points through memory long after the original event, the true area under your curve is larger than the sum of your immediate experiences. This means that front-loading experiences (while still planning for the future) tends to produce a larger total area than back-loading them, because earlier experiences have more time to generate memory dividends.

Core principles

6 total
  1. Life experiences can be assigned numerical values (experience points) based on personal fulfillment
  2. Your life is the sum of these experience points, visualized as a curve over time
  3. The goal is to maximize the total area under your fulfillment curve
  4. Memory dividends increase the area by adding ongoing returns from past experiences
  5. The shape of the curve matters as much as its height: front-loading creates more total area
  6. Both earning too much and spending too much can reduce the curve's total area

Steps

4 steps
  1. Define your personal experience point scale
    Create a scoring system for your experiences. Peak experiences might score 100 points, a pleasant dinner with friends 20 points, a routine day 5 points. The specific numbers do not matter as long as they are consistent and reflect your personal values.
  2. Score recent years
    Look back at the last 3-5 years and estimate the total experience points for each year. Note which years scored highest and why. Identify patterns: what types of experiences generated the most points?
  3. Project future years
    Based on your current trajectory (health, career, relationships, planned experiences), estimate the experience points for each of the next 5-10 years. Where does the curve peak? Where does it decline? This projection reveals whether you are on track for your ideal curve.
  4. Reshape the curve
    Identify specific changes that would increase the area under your curve. This might mean spending more on experiences now, investing in health to maintain the curve longer, or reducing work hours during peak-health years to create more time for high-point experiences.

Perkins' iPad gift to his father

When Perkins' father was too old and frail for new experiences, Perkins gave him an iPad loaded with digitized highlights from his 1959 Rose Bowl football season. Too old to create new experiences, his father derived enormous joy from reliving memories.

OutcomeThe father called it the best gift ever. The example demonstrates that at the end of the fulfillment curve, when new experience points are nearly impossible to generate, the memory dividend from past experiences becomes the primary source of fulfillment.

Common mistakes

2 traps
Maximizing a single year instead of lifetime area
Blowing all resources on one incredible year at the expense of future years reduces total area. The goal is sustained, balanced fulfillment across your entire life, not a single spike.
Ignoring the declining right tail
Many people plan as if their fulfillment capacity remains constant forever. In reality, the curve naturally declines as health deteriorates, making it critical to front-load high-value experiences.

Origin story

How this framework came to be

Perkins, trained as an engineer, approached life optimization the way he would approach any engineering problem: by defining a measurable objective function (experience points), creating a model (the fulfillment curve), and then optimizing for maximum total area under the curve.
