Definition
A "waste of effort" describes actions that don't produce worthwhile results. It's like trying to fill a bucket with a hole in it—you're working, but getting nowhere. This term highlights the frustration of investing time and energy into something futile. It suggests that the resources used could have been better spent elsewhere. Think of it as doing extra credit that doesn't boost your grade; you put in the work, but it doesn't pay off. This phrase often carries a sense of disappointment or regret, since it represents activity with little or no tangible benefit.
