Do you ever make up your own recipies when cooking?

I know a woman who will NEVER deviate from a recipe. But me…WTH! I glanced over a recipe for Quiche just to get the basic idea of it, then went in the kitchen and found stuff that I thought would work.
I made a thin crust from Bisquick, threw in a BUNCH of cheese, mixed up some milk and a million eggs and mild picante sauce…spied some cream cheese, threw that in…..and some mayo….it’s baking now. I’ll let you know! :)
