👉 Mushheaded is a term used in the United States and Canada to describe someone who has been overly focused on something or someone, leading them to overlook or neglect other important aspects of life. This can manifest as excessive attention to detail, perfectionism, or an inability to handle stress effectively. The term comes from the idea that when someone becomes "mushheaded," they may not be able to see things clearly and may miss out on opportunities for growth and development.
