Up a creek without a paddle
The idiom "up a creek without a paddle" describes being in a difficult situation with no apparent solution, likening it to being stranded on a river without a means to navigate. It underscores a state of helplessness and often implies a lack of preparation. For example, a project manager facing unexpected challenges without key resources would feel the pressure of impending deadlines and client expectations. Despite the difficulty, resourcefulness and resilience can help one find a way out of such predicaments.
