A cartoon brain wearing a tin-foil hat sits in a chair, reading a book titled 'Stuff I Believed Before M Degree'.

A whimsical, cartoon-style illustration of a human brain wearing a shiny tin-foil hat. The brain is sitting in a chair, reading a book titled 'Stuff I Believed Before My Degree' in bold, playful lettering on the cover. The style should be light-hearted, colourful, and humorous, with a touch of satire. The brain should look slightly embarrassed or sheepish as it reads, to capture the idea of cringing at old beliefs. Background simple and uncluttered, so the focus stays on the brain and the book. See more
