While searching for literature about her autistic perception, Maria Zimmermann decided to write and design a book about it herself. In doing so, she learnt how much the language you use to talk about something shapes your relationship to it. She speaks of discovery, not diagnosis; characteristic, not symptom; being autistic, not having autism; on the spectrum, not off the spectrum; sensory sensitivity, not sensory processing disorder; idiosyncrasy, not difficulty; different, not wrong.
