Reading Sun Tzu's Art of War at age 50

Changes in your fifties determine your success in life!
I ran non-stop for half my life toward the peak. However, as I reach my fifties, I start to feel in danger. I need to prepare for retirement, but the future after that is unclear, my self-confidence is declining during the process of business and re-employment, there are moments when I feel unfair in my relationships, including at home, and my position in society is gradually shrinking along with my health. Save money. Fifty is the inflection point when life begins to change in a different direction. How can you prepare for an uncertain future and protect your life?
The answer lies in Sun Tzu’s The Art of War. If you're in your fifties and want to navigate life's multiple risk sections smoothly, make a change! “The Art of War” is a timeless masterpiece that Napoleon always carried with him on the battlefield, that SoftBank's Masayoshi Son revealed as the secret to his success, and that created today's Bill Gates. In the best military strategy book of the Spring and Autumn Period, which has been read for 2,500 years, Sun Tzu wrote, “Achieve victory according to the opponent’s changes and circumstances (先勝求戰).” Just as we must change our strategy at any moment to suit the enemy's situation during war, we must also respond to various variables in life with changes.
Change begins with “knowledge and knowledge,” which runs through all of Sun Tzu’s The Art of War, that is, knowing the other person and knowing oneself.

'What changes have come to me since I turned 50?'
'How will life change after fifty?'
'How should I change myself?'

The result of this kind of protection is “no defeat in all battles.” It means that there is no danger even if you fight a hundred times, and burning means true victory. When you reach the age of fifty and think about the future, when you need unwavering preparedness in any situation, and when you want to face the years after fifty with a comfortable mind, let's seek change with the wisdom contained in Sun Tzu's The Art of War. This is preparation to win the battle of life.

2,500 years of strategies to prepare for an uncertain life
At the end of the Spring and Autumn Period, when competition for hegemony among feudal lords was fierce and the political situation of the country frequently changed due to frequent mergers and acquisitions of powerful people, Sun Tzu wrote a war strategy book, The Art of War. It was to survive the chaotic period safely. Osip's life today is unfolding similarly to his grandson's situation 2,500 years ago. This book selects the 39 most essential strategic moves from “The Art of War” for Fifty, who feels at risk. Through this, your success in life will be determined by whether or not you come up with a new strategy after fifty.
First, it is a strategy to gain without fighting. Sun Tzu said that it was best to capture the enemy 'completely' without blood on his sword. If you attack and destroy the enemy directly, not only will the war cost be high, but the cost of recovering the occupied territory will also be high. The best strategy is to win by default without fighting. One of the methods for this is the 'scare' of Han Xin, the general of the Han Dynasty. In order to take control of Qi, Han Xin sent a well-spoken envoy to scare him by saying, “Great General Han Xin is a master general who defeated the 1-strong Zhao Dynasty with 20 soldiers.” By making the other side feel the gap, they lost the will to fight. The Qi Dynasty, frightened by Han Xin's power, immediately surrendered. In your fifties, rather than engage in personal, visible competition, it is wise to create a 'super gap' to prevent others from overtaking what is yours in the first place.
Second, it is a strategy to know a little more about anything than others. Sun Tzu argued that in order to lead the war as the general intended, he must keep his soldiers informed of important military plans. This asymmetry of information has become a practice for profit even in modern times. In your fifties, you need to find out what you know more than others and be able to use it positively.
Third, it is a strategy to turn weakness into strength. According to Sun Tzu, ‘force’ means creating a situation to one’s advantage. This can be understood as ‘flow’. If you ride a trend that is favorable to you, it is easy to remain strong in the future, but if you ride a trend that is unfavorable to you, it is difficult to transition from weakness to strength. So the ability to shift momentum is needed. In your fifties, you need the courage to break away from the desire to settle for success or conform to failure.

Imitate the spirit of change and burning at the inflection point of life.
Sun Tzu’s favorite strategy is “first and last fight.” This is no different from the strategy of Admiral Yi Sun-sin, who led the victory in the Battle of Myeongnyang, by first creating a winnable situation and then fighting. At that time, Admiral Yi Sun-sin, who faced the Japanese army's 13 military ships with 32 Panokseon and 330 Chotamseon, first identified the weaknesses of the Japanese army and the strengths of the Joseon navy and planned a strategy to maximize them.
When you reach your fifties, it can be said that it is also a Zen monk's oral tradition to prepare a new life strategy for the future. In addition, through the heart that pursues change, you can go through the inflection points of life where various changes are complicatedly intertwined, without risk, and this is the spirit of fire that fifty people need. Ultimately, the grandson has one thing to say to Osip, who wants to stay away from danger and achieve victory in life. Live differently tomorrow than yesterday!
We think of the period after 50 as a time when life begins to decline from its peak and everything gradually comes to an end, but in fact, we still have the afternoon of our lives left. If you want to wisely cope with changes in life, if you want to turn weakness into strength after 50, if you want to overcome anxiety and fill yourself with confidence, get the wisdom from “The Art of War”. If I read the situations surrounding me through this book and find the changes I need, I will be able to finally win in the afternoon of my life.
