In my opinion, there is a way to improve one's self-cultivation: observation+self-reflection, or to put it another way: "A threesome requires a teacher." Observe other people's self-cultivation places (such as the way they treat friends, strangers and family members), reflect on their own practices and improve them.
1, increase experience. I really envy the very calm expressions on the faces of those middle-aged and elderly people. After years of baptism, although there are many wrinkles on their faces, they have a calmer heart and can often handle things smoothly. I think when a person consciously increases his experience, observes different people, experiences different things, travels different places, and encounters something, he should keep his inner peace and calmly deal with it. Give a humiliating impression and naturally feel educated.
2. introspection. An old saying goes: three rescues a day. Master Kong said, you know!
I hope this helps.
