Work with your type, not against it
Forcing a wolf to wake at 5 AM creates chronic circadian misalignment. Schedule deep work during your peak, and protect your biological wind-down time.
Key Takeaway
Know your chronotype. Schedule your most important work during your biological peak and respect your body's preferred sleep window.
