The book is a masterclass in the creative process. Munari argues that creativity is not a mysterious flash of genius, but a logical process. The title summarizes the method: you do not start with a fully formed idea; you start with a basic element, manipulate it, and that action leads to the next step.

Munari emphasizes "trial and error" not as a failure, but as the primary engine of creation. You cannot know the end result at the beginning. By manipulating a material (paper, wire, paint), the material itself suggests the next move.

(often translated as "One Thing Leads to Another") is a seminal work by Italian artist and designer Bruno Munari , first published in 1981. Subtitled Notes for a Project Methodology , the book serves as a practical manual for anyone looking to solve problems through a structured design process.

: Munari distinguishes between "fantasy" (pure imagination) and "creativity" (imagination applied to solving a practical problem).
