Getting the right idiom

This year, the NTT calendar has Japanese four character sayings, along with an explanation, and English translations. There's one every two months, so for January and February, we have the Japanese

意気揚揚：よし、頑張ってみるか待ってましたその言葉
( musing . . . )

I've been waiting to hear you declare you are going to fight? Or maybe just "We're going to do it!"

Tricky little phrase, there. And an interesting choice for a Japanese calendar quote.
