Whether a person's life is happy depends not on whether he is young and beautiful, nor on whether he is rich, but on whether he has a healthy mental state and a sincere heart.

Man's life is long and far away. In the long life, we will meet many people and experience many things. Some of them are moved beyond words, some are grateful from the heart, and some are inevitable hardships and grievances. No matter what you encounter, you must learn to have a tolerant and sincere heart.

There are sunny days, people have good and evil, and there are many things in nature that we humans can't do. We can't change the world, nor can we change others. What we can change is only our own mentality and a philosophy of tolerance towards the world and people around us.

Learn to be sincere, your heart will be open-minded, you will be grateful for all the beautiful things in the world, and your life will be much happier.

I often say to myself, be a modest and contented person and treat all the sufferings in life as a gift from God. How can you know warmth without experiencing cold, and how can you know sweetness without experiencing hardship? I am willing to hide all the pain and unhappiness in my heart, and face the world with a sincere heart as the experience that life has given me.

Thank my parents for giving me life, hardship for giving me strength, frustration for giving me courage, deception for giving me wisdom, poverty for giving me faith, and contempt for giving me self-esteem.

I thank the mountains and rivers for giving me aura, the sun and the moon for giving me warmth, the blue sky for giving me transparency and clarity, and the Millennium culture of the yellow land for giving me a simple and kind heart.

Putting a piece of alum in water can precipitate the dregs in the water, cultivate a sincere thought in our hearts, and precipitate a lot of impetuousness and anxiety.

Learning to be sincere means learning a good attitude towards life. When you are grateful for everything in the world and everyone around you, you can eliminate all the grievances and dissatisfaction in your heart, and the world in your eyes will have no dust. A transparent and clean heart is your happy place.

Happiness is the most precious wealth in life and the natural expression of life emotion. Happiness should be absorbed by your own heart. A sincere heart is easily moved, and a sincere heart is full of gratitude, so you will be happy and satisfied.

A casual message, a gentle greeting, a kind smile and a distant blessing can all express a sincere heart's love for life. Learn sincerity, you will learn to be free and easy, learn sincerity, and you will learn to be happy.

Sincerity is a philosophy of life. Sincerity will make you many friends.

Sincerity is an attitude towards life, which will make you indifferent to fame and fortune and be content.

Sincerity is a person's indelible conscience, always with sincerity, it will let you know the grace of dripping water, and the spring will repay you.

Learn to be sincere, and life will give you brilliant sunshine;

Learn to be sincere, and life will be full of love and hope.
