What is Zealous? help!
"As she looked, aghast, at the pony that was tethered in her front lawn and munching comfortably on her flowers, she realized how just how alarmingly she’d underestimated his zeal to impress her. She’d also underestimated the size of his bank account and his brain: impossibly vast and impossibly tiny, respectively.
'I did not mean it when I said I wanted a pony,' she explained to him later through gritted teeth.

Zeal is the noun form. Usually, you’re zealous for a cause or purpose. It means you’re super-eager and super-committed to making something happen, and you’ll go to great lengths for it. It can have a bit of a negative connotation, and it’s more often seen in the form overzealous, which is being excessively eager, to the point of being a fanatic.
