Here are some things I learned from Lindy Hop that have influenced my Improvisation:
1) There is someone with you, whether you remember it or not.
2) It's better to play with the person with whom your are dancing than some other person about whom you may be wishing.
3) When someone does something you don't expect, it's way more fun to accept it and perhaps augment it than it is to put up defenses.
4) What's the point of fear? It's not like there's a bear on the dance floor.
5) Listening is more than hearing. Using my senses is an important way to tune in to the world around me, not to mention the person with whom I'm dancing.
6) Everyone was a beginner at some point.
7) There's always more work to do.
These are just several notions that come to mind after more than a decade of dance.
This is to say that it's worth it creatively to explore the world around you. If you do something fun, it can't help but carry over into all of your creative endeavors.
I'm sure there are thoughts about how my return to improvisation has enriched my dancing. Not to mention my more recent exploration of yoga. I'll have to let those thoughts simmer for a bit.
