Humble at work

What does humility mean?

Today, I was told at work that I am not humble. That I assume as though things are a given to me and that I need be more humble.
In the workplace, as I have come to learn, being humble means beign like I sponge...take it all in and dont release until squeezed!

Yep, this is the new feedback at work. The problem is that when one has met her entire objectives for the year, that are measured as revenue for a company, exceeded expectations and has a loving client base...one wonders what the hell a sponge has to do with a promotion?!

Am I to be the next spongebob square pants cartoon character?
You tell me.
