What does it mean that the purpose experiment?

Try different activities and causes to discover what generates purpose for you.

Example: A thirty-eight-year-old product manager named Mara had spent three years journaling about purpose, reading books about calling, and taking personality assessments — and she still could not answer the question "What is my purpose?" with anything more specific than vague abstractions about making a difference. Then she stopped thinking and started testing. She designed three two-week experiments: volunteering at a coding bootcamp for first-generation college students, building a small open-source tool for nonprofit data analysis, and mentoring a junior colleague through a difficult project. The bootcamp left her energized but frustrated by institutional bureaucracy. The open-source tool absorbed her so completely she lost track of time three nights in a row. The mentoring was satisfying but did not pull her outside working hours. Six weeks of experimentation told her what three years of introspection could not: her purpose lived at the intersection of creation and contribution — building tools that extended other people's capabilities. She did not discover this by thinking harder. She discovered it by running experiments and paying attention to what her energy, attention, and engagement actually did.

Try this: Design and run a purpose experiment portfolio using the protocol below. Step 1 — Generate hypotheses: write down three to five candidate purpose activities, each connected to one of the four pathways explored in L-1425 through L-1428 (contribution, creation, mastery, care). Each candidate should be specific enough to test: not "help people" but "teach a weekly workshop on budgeting basics at the community center." Step 2 — Design the test: for each candidate, define a two-week pilot (drawing on the protocol from L-1115). Specify what you will do, how often, where, and with whom. Identify the minimum commitment that gives the activity a fair test — substantial enough to generate real data but small enough that failure costs almost nothing. Step 3 — Define your metrics: before you begin, write down what you will track. At minimum, track energy level after each session (1-10), spontaneous thought frequency (how often the activity enters your mind unprompted), and willingness to continue (would you do this again without obligation?). Step 4 — Run two pilots simultaneously over two weeks, then run two more. Step 5 — After four weeks, compare the data. Which activities generated energy rather than depleting it? Which occupied your thoughts without being asked to? Which would you continue even if no one was watching? The answers are your experimental evidence for where purpose lives.
