Cosmos는 "내 삶에서 가장 소중한 것은 무엇인가요?"와 같은 깊은 성찰의 질문부터 "내가 가장 좋아하는 향기는 무엇일까?" 같은 일상의 소소한 질문까지, 총 365개의 질문이 순환 구조로 제공되는 특별한 공간입니다. 다른 사람들의 기준, 책에 나와 있는 현명한 답도 아닌 오직 나만의 속도와 언어로 부담 없이 이 질문들에 답해보세요. 나를 마주하고 생각과 감정을 기록하다 보면, 자연스럽게 나의 변화와 생각의 흐름이 차곡차곡 쌓이게 됩니다. 이렇게 쌓인 소중한 기록들을 통해 과거와 현재의 답변을 비교해 보세요. 내가 어떻게 변해왔는지, 어떤 가치와 생각이 단단해졌는지, 무엇이 새롭게 자리 잡았는지를 한눈에 확인할 수 있습니다. Cosmos와 함께 시간이 흐르며 쌓이는 변화의 흔적을 바라보면서 스스로를 이해하고, 나만의 길을 조금씩 확신하게 되는 순간을 경험해 보세요.
