How it's used

This idiom is a vivid metaphor describing someone who begins a task with high energy or a grand display but fails to follow through to completion. It is frequently used to criticize a lack of perseverance or consistency in work, studies, or personal projects. The contrast between the impressive initial display and the disappointing conclusion makes it a common way to express frustration with someone's reliability.

Examples

He always starts projects with great enthusiasm but never finishes them.
Don't just start strong and then give up, you need to keep going.

Common phrases

to do things with a strong start but a weak finish

Common mistake

Learners often mistake this for a simple description of failure, but it specifically emphasizes the contrast between the strong beginning and the weak ending. It is not used for tasks that were difficult from the start, only those that were abandoned halfway through.
