Paint...is it that HARD to decide??

I admit it, I am the world's worst at making decisions!! I second guess myself WAY too much. We have been trying to pick a paint color for the nursery. Poor Emmerson Claire's room has turned into a checker board in shades of pink, aqua, and grey.  Every color I pick in the store looks completely different on the wall. We are currently on our 12th sample color!!  Yes, I said TWELVE!!! We have probably spent more money on samples than we will on the actual paint, but hey...it WILL be exactly what I imagine in my head! Hope to have a painted room by Sunday, fingers crossed!! Pictures below were taken after 8 samples...
