ChatGPT-5 reflects the latest update
AI Survival Strategies Chosen by 38 Companies, Including Samsung

"AI Strategy Class" is a practical book that can be immediately applied by anyone who is new to ChatGPT and AI, has given up on using it, or is slow to use it.
The author has collaborated and lectured with 38 companies, including Samsung, and has condensed his experiences in driving innovation through the use of AI in the field into this book.

We've systematically organized everything from AI concepts and the basic mindset of the AI ​​era, to question design, AI model selection, and prompts for immediate use, so even AI beginners can follow along step-by-step, from the basics to practical applications.
It reflects the latest model trends such as ChatGPT-5, and also provides a strategy to use necessary AI such as Gemini, Claude, Midjourney, Suno, and Beo3 at the necessary moment.

However, simply knowing the latest features won't enable you to leverage AI for long. The real weapons that will keep AI useful even after updates are the core fundamentals: questioning, reasoning, and mindset.
This book will equip you with the latest trends and practical know-how, as well as the fundamentals that will withstand any change. Whether you will constantly keep up with the changes in the AI ​​era or lead the way will be determined the moment you open this book.

How AI Can Transform Your Daily Life and Work in an Instant

From the moment you turn the pages of this book, your day will change.
Using AI in every moment of your life—10 minutes before a meeting, a week before a trip, a free weekend morning, or at the end of the month when you need to organize your household accounts—will improve your work efficiency and enrich your life.

The author emphasizes questioning techniques that go beyond simple searches and instead use repeated questions as if conversing with AI to accurately derive desired answers.
The appendix of this book is designed to help you apply the questioning techniques directly to your daily life.
Sixteen categories, including cooking, childcare, learning, reading, work, hobbies, travel, various planning, health management, and household account management, and over 250 sample questions are included in the book's appendix.
By using the included question notes, you can go beyond using the provided examples and create your own customized prompts.

Here, we are giving away a limited edition of the first paper book, “A Super Simple Handbook to Make Chat GPT Your Personal Secretary,” so that readers can see for themselves and follow along to turn AI into their own personalized secretary with just one setup.

AI's New Survival Strategy: Time is running out to get ahead.

According to a domestic survey conducted in 2025, 67.4% of workers who use AI at least once a day responded that “work productivity has improved by more than 50%.”
In contrast, only 6.9% of those who rarely used AI reported increased work productivity. The prediction that those who use AI will outperform the competition is hardly an exaggeration.

And ChatGPT is the most widely used AI model among various AI models.
Once you master ChatGPT, you can easily learn how to use other AI tools and discover the most use cases and know-how.
So, now is a good reason to stop thinking of ChatGPT and AI as novelties and start learning how to use them.

"The choice is still yours, but time is running out. Your competitiveness in five years will depend on whether you learn AI or ignore it.
If you don't start now, it will be twice as difficult in a year, and ten times more difficult in three years." _From the prologue

If you learn AI now, you will be ahead, but if you learn AI later, you will be left behind.
There is not much time left to move forward.
