Life long doodler here. Have had many teachers and lecturers express their consternation at me, but I persist. I often find it necessary to prevent my mind sort of "zoning out" which is unpleasant. I always remember a particular incident, when I was 15, a history teacher got very annoyed and went through my entire exercise book where the left-hand page was filled with some (IMO) excellent robot/human hybrids, and he used a pen to deface every last one of them. I didn't enjoy that class, apart from the drawing, but I did go on to top the grade in that semester. I strongly believe it was because of the drawings, not in spite of it.
