It's a recent thing.
After I finished my lecture, I was asked by an audience member what motivated me to do so much.
I feel ashamed to say it, but if I had to rate it positively, I would say it was 'wisdom given from love.'
I think the source of the 'wisdom of life' I received while working with someone I loved more than myself was the love I practiced.
He truly loved his family more than anyone else.
When I was in the education field, I loved and cared for my students more than anyone else.
During the Japanese colonial period and communist rule, there was no room for love.
So, I wanted to be with my students with the belief that 'education with love changes the world.'
Building a Republic of Korea overflowing with freedom and humanity was bound to be my life's mission.
Although a hundred years is not enough, I console myself by thinking that if I have acquired the wisdom I want to pass on to future generations, then the life I have been given will have manifested as the life and value of all of us.

There is a bigger challenge to aging gracefully.
It's beautiful emotions and emotional health.
We must embellish our thoughts and feelings.
It is a mental task that is several times more difficult than clothes or face.
The most important thing is desire.
As we get older, we should reduce our greed and let wisdom take precedence.
However, as our intellectual level declines and our self-control weakens, we are more likely to fall into the desires that we could not satisfy in our youth.
It also takes me back to my greedy childhood.
If you add dementia to that, you become an old person you don't want to see.
You could be a grandfather fighting with your grandchild.

There are no such old people around me.
However, there is a potential risk of making the mistake of being greedy for money and fame.
These are people who mainly compare themselves to others or cannot overcome desires they did not have in their adulthood.
To grow old gracefully, one must abandon greed, or in other words, possessiveness.
A wise old man turns the object of his desires to his juniors.
You must become a senior who praises and nurtures your juniors and disciples.

There is a saying that the most Korean things are global.
That concept is an exaggeration.
I believe that what is most human is what is most global.
All nations and peoples are evaluated as global while preserving their humanity.
Korean things also have a special quality that is embedded in the universality of humanity.
We ourselves are the artists who create that specialness.
When we organize our thoughts, what is important to us is artistry that has human commonality.
The key is the creative spirit of the artists themselves, possessing their own human universality.
Such Korean uniqueness will come together to create global universality.

Comparing my 30s to those of my 30s, there have been many changes in all aspects of society.
Youth and old age are becoming shorter, and middle age takes up more than half of one's life.
The middle age period, when we work, grow, and develop our character, lasts from our thirties to eighty.
Average life expectancy has increased and healthy life expectancy has also improved.
It has become a world where everyone can demonstrate their rich mental creativity.
Even if you cannot become a visionary or a pioneer, it is essential to make an effort to adapt to such a society.

Living areas and spaces are also exceeding expected limits.
In order to adapt to these changes and developments, we must not accelerate our own aging.
In my generation, sixty was considered the beginning of old age.
But I didn't think I was mentally old until I was eighty.
The longer middle age means that the world has become one where people can grow up and work while still being young.
Our given task and hope is to autonomously create a better world.
