Poincare's work habits have been compared to a bee flying from flower to flower. Poincare was interested in the way his mind worked; he studied his habits and gave a talk about his observations in 1908 at the Institute of General Psychology in Paris. He linked his way of thinking to how he made several discoveries.
The mathematician Darboux claimed he was un intuitif (intuitive), arguing that this is demonstrated by the fact that he worked so often by visual representation. He did not care about being rigorous and disliked logic. (Despite this opinion, Jacques Hadamard wrote that Poincare's research demonstrated marvelous clarity. and Poincare himself wrote that he believed that logic was not a way to invent but a way to structure ideas and that logic limits ideas.)
