A person who has difficulty making decisions or cannot decide on things is often referred to as "indecisive" or "indecisive person." Being indecisive means having trouble making choices or reaching conclusions, which can lead to uncertainty and hesitation in various aspects of life. Indecisiveness can be caused by various factors, including fear of making the wrong choice, lack of confidence, or being overwhelmed by too many options. It's a common human trait, and many people experience periods of indecisiveness at different points in their lives.
