Why am I always so busy? Why am I always short on time?
There's a reason why we're busier as technology advances.
“It wasn’t my fault I ran out of time!”

Know the 6 secrets of people who don't waste time
You'll find yourself with unexpected freedom, and all your luck will naturally improve.

'I already subscribed to Netflix, so I can't afford to lose.' I stubbornly watch one more episode.
I watch YouTube shorts and Instagram reels to keep up with future trends.
Another hour or two passes by in a flash.
As technology advances, the amount of information explodes, and we need to prepare for an uncertain future with videos and entertainment that we can enjoy.
We are bound to run out of time every day.


Yes, that's right.
“It wasn’t my fault I was running out of time!” The new book, “The Essentials of Time Management,” is a book that turns the frame of time management upside down.
It's not my fault that I'm lacking time, it's my surroundings.
Even though life expectancy is increasing due to the explosive increase in 'information volume', multifaceted 'human relationships', and unpredictable 'wealth opportunities', the time available is finite, so we are bound to always be short of time.
So, I say that if you just learn the skill of balancing yourself and the situation around you, you will have more freedom.

So I prepared.
《Time Management Essentials》 is a collection of 100 famous books that contain the know-how of people who don't waste time, and has compiled only the 'great ways to use time' into a single volume.
The author, a former management consultant, is an expert on time management who has been reading business books for 40 years.
The point is that it is something that has been put into practice and has seen results.
If you apply these ingenious time management tips to your life, you too will experience the magic of doubling your 24 hours.

We have so much information to process on our own that we don't have enough time.

Maybe it's not my fault that I constantly struggle with time management.

Therefore, checking and deciding on the deadline as soon as work begins holds the key to reducing time.

One of the most interesting books that explores the differences in the concept of productivity is called “Productivity.”
Japanese and American companies are said to differ in the qualities and training methods they employ in recruiting talent in two areas: leadership and productivity.
