What does everyone needs it and yet almost nobody takes it even when it is available?

The answer to this riddle is "advice." Everyone needs advice at various points in their lives to help make decisions or solve problems, yet many people hesitate to seek it out or follow it, often due to pride, fear of judgment, or a belief that they can handle things on their own. Despite its availability from friends, family, or professionals, people may overlook the value of external perspectives.
