What is even keeled?

"Even-keeled" is an idiomatic expression used to describe a person who is calm, balanced, and composed, particularly in situations that might cause stress or emotional fluctuations. The term is derived from maritime terminology, where a "keel" is a structural part of a ship that runs along the bottom, providing stability. When a ship is "even-keeled," it means that it is stable and not leaning to one side. Similarly, an even-keeled person maintains a steady and balanced demeanor, exhibiting consistency and rationality. This quality is often admired in both personal and professional settings, as it suggests reliability and the ability to handle challenges without overreacting.
