어제 오래간만에 예전에 같이 프로젝트를 했던 어린 친구들을 만났다. 그 친구들을 보면서 '마태효과' 라는 말이 생각났다. 그 친구들에게 일어난 일이 정확히 그 말을 설명하고 있다. '마태효과' 란 성경 마태복음에 나오는 '있는 자는 더 넉넉해지고 없는 자는 있는 것도 빼앗기리라'는 구절에서 유래했다. 처음에는 어렵고 힘들었겠지만, 그들이 버텨낸 시간 만큼 축적된 경험과 쌓인 지식은 어느새 그 친구들을 크게 성장하게 만들었다. 이제 내 도움이 없더라도, 그들만의 방식으로 잘 헤쳐나갈것 같다. 나의 글쓰기도 그렇게 무럭무럭 자라났으면 좋겠다.

첫 글쓰기이다. 어떤 글을 써야 할지 아직은 잘 모르겠다. 그냥 생각나는 대로… 하고 있는 일, 회사일, 집안일, 내가 경험하는 모든 일들을 일단은 두 서 없이 적어 본다. 그 안에서 느끼는 감정이나, 생각들을 끄적여 본다.
