Idioms for Uncertainty

Life rarely follows a straight path. Just when you think you’ve got everything figured out, uncertainty sneaks in and changes the game. Whether it’s about a career choice, a relationship, or tomorrow’s weather, we often find ourselves unsure of what’s next. That’s where idioms for uncertainty come in handy. They help us express confusion, hesitation, or unpredictability with creativity and color.
