About the Book
University College London’s research found it takes 66 days to form a lasting habit — not 21. This book is built around that finding. 66 Days Success Formula is the documented journey and practical system for anyone who wants to stop relying on motivation and start building the discipline that compounds.
It covers physical performance, mental performance, time management, positive language, and human psychology — combined into a 66-day challenge you can start today.
The Author’s Results
Half-marathons: 15× completed. Books read: 100+ in one year. (This is real proof the system works.)
The data demonstrates both consistency and progress in multiple areas of life—fitness, endurance, and knowledge acquisition.
“She is an inspiration to all the immigrants and she also proved that ‘Where there’s a will there’s a way.’ Coming from a different country and taking a risk to establish a business from scratch needs a lot of courage.”
