A decade after publishing "Grit," Angela Duckworth has revised her thinking. She now fears that teaching to "grind for the sake of perseverance" leads to burnout. True, sustainable high performance comes from a genuine passion for the craft, which makes the required hard work feel natural.

Grit isn't just about perseverance through hardship. It's the ability to do something consistently over a long period. Jubin argues this is only possible when the work itself gives you energy and you genuinely enjoy it. This insight connects passion directly to resilience, suggesting you should align your career with your energy sources.

While perseverance is crucial, focusing solely on "grinding" is a mistake. Angela Duckworth, author of *Grit*, regrets not balancing her message with the importance of passion. The ability to persevere in a field you don't love is a direct path to burnout.

High-achievers who pursue grueling endurance challenges are often driven less by a love for the 'grind' and more by a profound curiosity. The core motivation is an intrinsic desire to understand the experience and discover their own limits, without fear of the difficulty itself.

While grit is important, being pulled along by genuine curiosity is a more sustainable motivator than relying on willpower to push through rough patches. This innate drive to explore and learn prevents burnout and leads to discovering novel business opportunities without feeling like a constant struggle.

Passion isn't just about enjoyment; it's about an innate drive to learn. The best indicator that you've found your calling is when the process of acquiring new skills and knowledge in that field feels like a hobby, not work.

Perseverance isn't about forcing yourself through unenjoyable tasks. It's about finding a version of a habit that you genuinely find fun and engaging. The person who enjoys the process is more likely to stick with it through challenges, making them the most dangerous competitor.

Using "I'm not passionate about this" as a reason to quit is often a way to rationalize an inability to handle difficulty and do repetitive, unenjoyable tasks. True progress requires enduring these things to achieve a meaningful long-term goal, regardless of day-to-day feelings of passion.

People with a strong calling don't just work harder out of sheer will. Research indicates the primary mechanism is increased enjoyment of the work itself. This positive feeling directly translates into greater effort on relevant tasks, supporting the "love what you do" axiom.
