The emperor of review by Cyrus Oh

In the fiercely competitive digital age, 'know-where' is essential for survival.
If you are unaware of effective search techniques and the best use of smartphone apps and websites, you're the slowest turtle in the race of life.

But this book transforms even those who consider themselves turtles into smart, swift eagles!
It introduces powerful tools (some of the best and most popular apps and websites in the world) that can improve almost every aspect of life, from work efficiency and convenience to learning, self-development, hobbies, and entertainment.

This book may be small, but the value it can bring is immense.
It will be your booster for quick and powerful achievements!
