Energy Ecology. Designing work around actual biology

You've built a productivity system assuming you're a machine with constant output capacity. You're not. Your brain and body cycle through phases: high focus, low focus, deep work capacity, administrative capacity. These cycles exist whether you acknowledge them or not. Fighting them wastes enormous energy. This book teaches you how to sync your work with your actual cycles instead of fighting them.
You'll learn to map your genuine energy patterns across days, weeks, months, and seasons. You'll discover that the most productive people aren't the ones with most willpower-they're the ones who structure work to match their actual availability. You'll learn that designing around energy variation isn't laziness; it's alignment. For anyone worn out by trying to maintain flat productivity, this shows how to organize your work so intensity itself becomes sustainable.
