The idiom about being lost without direction is "lost", which is usually used to describe people who feel at a loss without a clear goal or direction. Here are some examples: - He was now completely lost. He did not know what to do or which direction to go. - He didn't have a specific goal, so he always felt lost in his work and couldn't use his abilities. - If a person did not have a clear direction, then his actions and decisions would easily become blind and disorderly. - Disorientation could be manifested in many ways, such as losing confidence, losing a sense of direction, and being unable to concentrate.
