Editing Vincent van Gogh (section)

== '''Career and Obsessive Focus on Art''' ==
Van Gogh’s young adulthood was tumultuous, marked by false starts in various careers – art dealer, schoolteacher, lay preacher – before he committed fully to painting in his late twenties. This period highlights his struggles with adapting to conventional work environments and his eventual monotropic obsession with art. As a trainee art dealer in London and Paris (1869–1876), van Gogh initially did well when dealing with catalogs and paintings (things that fit his interest), but he faltered badly when the job demanded social schmoozing with clients.

Colleagues noted Vincent’s ''“inability to form satisfying relationships with others”'', which hampered any role requiring customer service [https://us.jkp.com source]. He would lecture potential buyers on the spiritual value of art instead of politely selling – behavior that, unsurprisingly, led to his dismissal. Fitzgerald points out that ''“poor social interaction and lack of instinct in personal life”'' often derail people with Asperger’s in typical careers, which is evident in van Gogh’s failure as an art dealer despite his encyclopedic art knowledge. Each time he tried a new path (bookseller, then missionary preacher), his rigid, eccentric approach and social naivety resulted in conflict or firing – a pattern common among undiagnosed autistics struggling in the neurotypical work world.

By 1879, after a traumatic attempt at missionary work in Belgium (where he overzealously gave away all his possessions to peasants and was deemed “too extreme” by church authorities), van Gogh’s life entered a phase of singular focus on art. In the early 1880s, back in his parents’ home, he drew obsessively. His day followed a repetitive routine: long solitary walks to observe laborers and nature, then hours of drawing studies of figures or landscapes, barely stopping for meals. This ''“hyperfocus”'' on creative work to the exclusion of other activities is a well-known Asperger trait.

Van Gogh would sometimes sketch the same subject dozens of times – for instance, peasants’ heads or a particular tree – a form of repetitive practice and ''“perseveration”'' that mirrors the stereotyped behaviors of autism, now channeled into artistic mastery. As Fitzgerald notes, ''“persons with Asperger syndrome often have an enormous capacity for repetitive practice and detail,”'' which in van Gogh’s case manifested as painting and repainting similar motifs with slight variations.

His sensory sensitivities also began to shape his art during this period. Vincent experienced colors and sounds intensely – letters to Theo describe the “symphony” of colors in nature and how certain hues “stab” his senses. This aligns with the heightened sensory perception in autism; many on the spectrum report that colors are unusually vivid or sounds extraordinarily acute. Van Gogh’s later legendary color palette (the blazing yellows of sunflowers, the swirling blues of ''Starry Night'') can be partly understood as the expression of a visual system tuned to high gain – he truly ''saw'' those colors more intensely than others.

His fixation on particular colors at different times (for example, a ''“yellow period”'' in Arles where he painted almost everything in sunlit yellow tones) suggests a form of ''“restricted interest”'' in specific sensory experiences, not unlike an autistic child fixating on a particular hue or texture.
