Make Today Count: The Secret of Your Success Is Determined by Your Daily Agenda

The book emphasizes specific routines for success, but I wonder if these were based on research or personal experience. How did the author decide on these particular practices?

Some of these practices seem straightforward, but I’m curious if others struggled to stick with them or saw immediate benefits.

Since the book is very practical, I’m wondering if these routines are universally effective or if they need adapting for different lifestyles and cultures.
