In this Food for Thought, I use my experience of writing scientific publications to stress some aspects of the process that were especially significant for me, and from which I try to derive some general suggestions. These aspects include: strong interactions (co-evolution) between paper writing and some of my research directions; the pleasure of writing with co-authors; writing as a tool of scientific creativity; long scientific quests through several publications; the importance of writing books, if possible starting early in the career; being published, reaching readers, and contributing to the advancement of knowledge; and giving in to the pleasure of writing. I explain that I often seized unexpected opportunities that led me to develop ideas and write publications that influenced the course of my career, but I do not necessarily suggest that anyone proceed as I did. My motivation was the enjoyment of exploring new topics, and I wholeheartedly recommend that everyone give in to the pleasure of writing.
