Reflecting on oneself in English is commonly referred to as self-reflection or introspection. This term comes from the Latin words "intro" and "specere," which mean "to look within." An example sentence in English might be: "I spent some time in self-reflection, trying to understand why I made that mistake." In Chinese, this could be translated as: "我花了一些时间反思，试着弄懂为什么我犯了那个错误。"
