15 States of Inner Strength in Middle Age:

First, never ask others for reasons. Since it has already happened, the reason is no longer that important. The reason you want an answer is because you cannot solve the problem. If others want to tell you the reason, they will definitely主动 say no, telling you that they will not break the silence.
Second, allow everything to happen, whether good or bad. As long as it happens, it is a hurdle you must cross on your life journey. See all good things as a reward for your efforts, and all bad things as a way to avoid disaster and loss. A truly strong person does not like confrontation but accepts it calmly, allowing regrets in life, accepting the impermanence of the world, and the occurrence of mistakes, then continues to move forward lightly.
Third, unless it is a matter of life and death, do not tear your face with anyone. The world is vast, and you will meet again sooner or later. When dealing with people you dislike or who have hurt you, even if you retaliate fiercely, do so silently and without showing emotion. Adults should do this— even if they understand clearly, they will not lose their temper on the spot, at least not be the one to flip the table.
Fourth, do not pity anyone, even those closest to you, and do not expect pity from others. Pitying someone subconsciously carries their fate, creating enormous pressure for yourself. Seemingly noble, but actually foolish. The unfortunate often have their own flaws; sometimes, fools are more terrifying than bad people. The most worthy thing we love in this world is ourselves, who can move forward without burden. Only when you are strong enough can you help others carry burdens; otherwise, you will only sink into the mud.
Fifth, be able to accept all things calmly. Everything in the world has cause and effect. What seems accidental is actually inevitable by fate; it’s just that we, ordinary people, cannot see it.
Sixth, control your mouth, guard your heart, listen more, think more. Persist in what you believe is right, regardless of others’ opinions and views. Those who do not contribute money or effort are less likely to listen to your advice. Know your strengths and weaknesses, and learn to leverage your strengths and avoid your weaknesses. Such people are truly strong and capable of bearing.
Seventh, develop the habit of being independent. Cattle and sheep travel in groups, but predators only walk alone. You can have friends and partners, but still maintain the ability to be independent. This cultivates top endurance and thinking ability. Independent travel also shields you from external temptations and distractions, with strong focus and resilience.
Eighth, do not overly scrutinize your partner. Human nature cannot withstand testing, even those who are long-term companions cannot withstand detailed scrutiny. There is no absolute loyalty in marriage; everyone has their own desires and spirits. Infidelity is still infidelity. Living together is about learning to comfort oneself. You cannot want everything, as no one is perfect. The essence of marriage is a partnership.
Ninth, do not have too high expectations of human nature. When at the top, many will look up to you; when fallen, many will trample you. Don’t think that having many friends means you understand everything; going bankrupt once will reveal everything. Don’t think that having many backing will prevent you from seeing people’s true nature; once you fall into hardship, you will see people’s hearts. Understanding human nature means you won’t be disappointed. In life, only two things are reliable: your health and your ability to earn money.
Tenth, accept your experiences calmly. In this life, you will take the wrong paths, hit the walls, and fall into traps—none will be missing. Don’t get stuck in them or engage in meaningless internal conflicts. Learn to block out people and things that drain you.
Eleventh, as your energy increases, start understanding everyone around you. They are just on different frequencies—there is no good or bad, right or wrong. Because they show different states, they make different choices. Allow yourself to be yourself, and also allow others to be themselves.
Twelfth, speak with dignity, dress with integrity. In the worldly view, respect comes first for the clothes, then for the person. So when you are poor, don’t let others see your poverty or you will only become poorer. When wealthy, tell others that you used to be very poor.
Thirteenth, do not fear losing. Life is an experience. Anything you cling to in this life is not truly yours; we only possess it temporarily. Don’t fear harm—what can hurt you is your own karma. Prosperity is fleeting; once you see through it all, it’s just clouds. Endless worries, but once you let go, it’s a sunny day.
Fourteenth, accept your mediocrity. We are all mortals; there’s no need to pretend to have a perfect life. Even the most capable have flaws. Some like to pick faults in the poor, others find advantages in the rich. Learn to accept your dark parts. Allow yourself to make mistakes, accept setbacks, accept unreciprocated love, and bloom with regrets. This is the only way to reconcile with yourself.
Fifteen, every relationship ultimately is just a meeting. Those with intentions may feel burdened; those without, indifferent. Love is voluntary; don’t talk about owed favors. There are not so many people in the world who truly empathize—caring too much about others’ feelings will only make yourself suffer. When a thought arises, it’s a world apart; when it fades, it’s close again. Focus on yourself—that is the top trait of a strong person.
