Reading this book will save you reading any other time management book! For solid and practical ways to make better use of your time, Brian Tracy's 108 page book 'Eat that Frog!' is easy to read and a great summary of key time and life management principles. It includes helpful tips on the wise use of technology too.
The key principle of the book is the ability to concentrate on the most important task, to do it well and finish it completely. How does the frog come into this? To quote Brian, "Your frog is your biggest, most important task, the one you are most likely to procrastinate on if you don't do something about it. It is also the one task that can have the greatest positive impact on your life and results at the moment".
The rest of the book contains 21 short and practical chapters on how to achieve this.
