For significant projects, ask yourself: 'Would I do this for no money or even if it meant losing money?' If the answer is yes, it's a strong signal that the intangible benefits (learning, networking, fulfillment) are massive. The best projects, like a podcast or community, often pass this test.

Purpose isn't exclusive to high-status professions. Any job can become a source of deep purpose by connecting its daily tasks to a larger, positive impact. A NASA custodian can be "putting a man on the moon," and a parking attendant checking tire treads can be ensuring driver safety. Purpose is a mindset.

Philosopher Søren Kierkegaard, who spent his inheritance to fund his own writing, provides the ultimate test for professional passion: "Would you pay to do what you do?" This question starkly separates those driven by a love for the process from those motivated solely by monetary reward.

Worldly proxies for success like money, power, and fame are finite and can be traps that lead to burnout. A more sustainable North Star is the feeling of "abiding joy"—a generative energy that increases the more you tap into it. This feeling signals you're on the right path.

To find your true calling, divide your life into five-year increments. For each block, list what you loved doing and what others said you excelled at. The seven or so themes that repeatedly emerge point directly to your core purpose and passion, which often get lost in the pursuit of money.

To use the Japanese concept of Ikigai for true fulfillment, remove the "what you can be paid for" component. Instead, focus on the intersection of what you love, what you're good at, and what the world needs. This subtle but powerful modification helps separate your life's purpose from your job.

Once a creator achieves significant success, the guiding metric for their career should shift from financial ROI to personal happiness. Engaging in activities you genuinely enjoy, even if they seem less profitable on paper, will fuel your energy and compound your success across all ventures in the long run.

To uncover your primary driver among money, power, pleasure, and honor, use elimination. Forcing yourself to discard the ones you care about least reveals the one that truly motivates you, which is often the source of your future regrets.

The pursuit of wealth as a final goal leads to misery because money is only a tool. True satisfaction comes from engaging in meaningful work you would enjoy even if it failed. Prioritizing purpose over profit is essential, as wealth cannot buy self-respect or happiness.
