今天学了很多理论知识，脑子有点“烧”。有时候我会想，这些看起来抽象的概念，真的能用到现实生活中吗？但我也慢慢明白，理论并不是要立刻改变什么，而是让我们换一个角度看待世界。 Today I studied a lot of theoretical knowledge — my brain feels a bit overloaded. Sometimes I wonder, can these abstract concepts really be applied in real life? But gradually, I’m beginning to understand: theory isn’t always about immediate change, but about helping us see the world from a different perspective.
