Recognize the area in which you are most confident, manage it comprehensively, and develop it.
In order to find your own special talent and manage it appropriately, the concept of 'style' must come first.
Establishing your own style goes beyond simply becoming proficient at something; it adds meaning to your life itself.
In that sense, the secret to mastery is the act itself of having the awareness to figure out a style that suits you.

If you are only eager to imitate superficial performance, it is nothing more than imitation, and you cannot say that you have stolen the technology and made it your own.
The power to steal technology is fundamental to recognizing and revealing the implicit workings of the technology.
And by once again embodying the 'thought or consciousness' that has been revealed to the outside, you can make it completely your own.
Only after going through this series of processes can you completely steal the technology.

Professor Horie Ichino emphasized that these three strengths are clearly important capabilities even in ordinary companies such as corporations.
In particular, during the learning stage, it is essential to have the 'power to steal' the secrets of superiors or senior employees, and when you become a middle manager who has to manage several subordinates, you need the 'power to drive' to revitalize the organization, and when you become a senior manager, you desperately need the 'power to summarize and comment' to be able to ask appropriate questions and give advice on the work of subordinates rather than taking the lead and doing everything yourself.

The basic principle of summarizing is to leave the core and boldly 'throw away' the surrounding elements.
The most ideal summary is not one that simply throws away something because it is 'thrown away', but one that melts it into the remaining core in some form and gives value to the discarded elements.
Ultimately, summarizing is about understanding 'importance'.
There are many cases where most of the time in meetings is spent on formal reports, and important matters requiring decision-making are not even properly discussed.

The secret to mastery lies in developing the awareness to clearly answer the question, "What am I doing this for?"
This perception is like a microscope or telescope whose magnification can be easily changed.
For example, looking at the relationship between the elbow and wrist when holding or throwing a ball is a microscopic perspective.
On the other hand, analyzing what role a specific skill plays in one's overall playing style is a macro perspective.
As you navigate the vast spectrum of micro to macro scales, it's crucial to identify the technology you're aiming for and master it.

To regard style as the central concept of universal mastery is not simply to glorify individuality; quite the opposite is true.
The concept of style makes us more aware of the question of which lineage we should follow.
Awareness of which lineage one considers oneself to be a successor to.
If we call this 'genealogy consciousness', then this genealogy consciousness is the concept that plays the most important role in creating style.
When creating your own style, people who can serve as role models are called 'predecessors'.
The secret to mastery is to continually check your awareness of the problem of finding your own predecessor.

When you do something repeatedly, there comes a point where you learn how to do it more effectively.
Moments like this only come when you invest a certain amount of time and focus.
Only when you are completely immersed in that world and remain clearly aware of what you are doing for a certain amount of time can you finally grasp the trick.
Even if you practice for a long time, if you don't concentrate, the moment when you get the hang of it will never come.

Clarify the tasks required of you and perform them while taking into account your physical characteristics throughout your life.
This is the fundamental principle of style building, and how to truly master the universal principles of mastery.
If you learn the unique skills of a specific field while ignoring your own physical characteristics, you will not be able to directly utilize the skills you have painstakingly learned when the field or situation changes.
However, if you learn it properly through consistent transformation (style) in your own way, taking into account your own physicality, that transformation will have a positive effect on work in other areas as well.

When facing unknown territory, there is a huge difference in the results whether I approach it with the confidence that I can do well or with anxiety.
This wasn't something that could be said with just confidence and no basis.
Because you have experience mastering the universal principles of mastery, you can use that experience as a foundation to courageously challenge yourself in new areas.
People who are called 'first-class' have a clear sense of 'center'.
