Did you know what does  being on the ball mean?

   If you look at this English idiom  literally, it means to be either standing or sitting            on a ball—but  who would do that?

       If you’re on the ball it means that you’re very quick to understand certain things,            very   prepared for something or react quickly (and correctly) to a situation.

       For example, if you’re planning your wedding that is still one year away from now          and you’ve  almost finished with all the planning already, you’re definitely on the            ball because not many  people are that prepared!

       “Wow, you’ve already finished your assignments? There not due until next week,              you’re really on  the ball. I wish I could be more organized.”
