english: It's only when you're told that you're going to be working on this problem, and then you start procrastinating, but the task is still active in the back of your mind, that you start to incubate.
non_english: Alleen wanneer je weet dat je die dingen moet verzinnen en dat dan gaat uitstellen, dan ben je daar onderbewust toch mee bezig: je zit er toch op te broeden.
