"I read this and gained so much time, and my stress decreased significantly." ★ A global bestseller with a groundbreaking time management approach from Google and YouTube's "addiction professionals"! ★ In a world where we are "automatically driven by time," how can we live the life we truly want?

Author Jake Knapp worked at Google, and John Zeratsky worked at YouTube, both of whom have continuously researched the mechanisms to keep people's attention for "every minute, every second." They are "addiction professionals." Because they understand the mechanisms of human psychology so well, the time management techniques in this book are built from a thoroughly realistic perspective, stating that "human 'willpower' is almost useless." Furthermore, it points out that "no matter how much you increase productivity, you're just meeting other people's expectations," and it's not necessarily benefiting yourself.

Experience the amazing techniques in this book, and watch your "meaningful time" increase with each one you try!
