Putting the Banana in the Bag

Taking action that advances a situation, or pushes something or someone forward.

Putting an unripe banana into a paper bag makes the banana ripen faster.

Conversely, messing up or taking a step backwards from a goal would be taking the banana out of the bag.

"Will just bought that girl a drink and took her to the dance floor. He's really putting the banana in the bag tonight."

"You're gonna skip the gym again tonight Berkelee? Really taking the banana out of the bag smh"

"This banana is green. I'm going to put the banana in the bag so I can eat it with breakfast tomorrow"
