5200 weeks

Oliver Burkman wrote 4000 weeks, which I can't recommend enough.

"We live in an age of impossible demands, infinite choice, relentless distraction and spiralling global crises. Yet most productivity advice, like other modern messages about time, makes things worse. It encourages the fantasy that we might one day “get everything done”, becoming the fully optimized, emotionally invincible masters of our time. The pursuit of this limit-denying delusion systematically leaves us more busy, distracted, and isolated from each other – while postponing the truly important parts of life to some point in the future that never quite seems to arrive."

Why 5200 weeks instead of 4000? I plan to live to be at least 100 years old.
