Those who have achieved great success and great knowledge in ancient and modern times must pass through three realms:

1. Last night, the west wind withered the green trees, and I climbed up to the tall building alone, looking at the end of the world. This first realm.

2. The clothes are getting wider and wider, but I don’t regret it at all. I feel haggard because of the beauty. This second realm.

3. The crowd looked for him thousands of times, but suddenly looking back, he was there, in a dimly lit place. This is the third realm.

Explanation of three realms:

1. "Last night the west wind withered the green trees, and I went up to the tall building alone, looking at the end of the world." It comes from Yan Shu's "Butterfly Loves Flowers". The fierce west wind withered the green trees, and I thought about going up to the tall building alone, clearly seeing the distance and the end of the world.

In loneliness, people are more likely to reflect on themselves and understand their own pursuits better. When you are confused, you might as well try to think quietly alone and think about your future goals. As the saying goes, "Stand high and see far." Being at a high place can eliminate interference and not be confused by temporary smoke. When Du Fu climbed Mount Tai, he wrote "I will be at the top of the mountain and see all the small mountains at a glance", and he made a heroic ambition.

2. "The clothes become wider and wider, but I don't regret it anymore, and I feel haggard because of Yi" comes from Liu Yong's "Die Lian Hua". The original meaning of the poem is that the body becomes increasingly haggard due to longing for the beloved, highlighting the depth of the pain of lovesickness.

In "Human Words", it is used to describe persistence and persistence in pursuing goals. When you have a goal, the road to pursuit is arduous. In the process, you will encounter all kinds of difficulties, you may encounter a series of failures, and you may also be ridiculed. If you can't hold on and give up halfway, your goal will end up staying where you are.

3. "The crowd searched for him thousands of times, but suddenly looking back, he was there, in the dim light" comes from Xin Qiji's "The Sapphire Case". In the poem, the poet met an attractive woman during the bustling Lantern Festival. He was looking around in the crowd, but when he suddenly turned around, he found the woman in a dimly lit place.

In the process of striving for goals, as experience accumulates and abilities improve, when you have accumulated enough, you will have an epiphany, and the goals you set in the past will be achieved inadvertently.
