One of my favorite "you can just do things" experiences was one day thinking it'd be nice if our friend group had a group Christmas party ... and then just starting one. Kept it going five or so years, faded out after a while after people started taking turns and logistics piled up, but I'm proud of having pulled it off.
But man do they take a lot of time, money, and dedication to pull off well.
