Idiom of the Day:

Run out of steam

If you “run out of steam

,” this means that you lack the energy or motivation to continue doing whatever it is you are doing. And, like a steam engine for a train, you slowed down until you stopped altogether. Maybe you “ran out of steam” while running a race and finished by walking. Or perhaps you “ran out of steam” learning English and took a break from Hello Talk for a while! It happens. We all need a rest once in a while.
