Decisions, Decisions

Moving into a house, has caused a lot of decision's. Do we paint the kitchen blue and if so "What shad of blue?", is going to be to dark to light. Do we wall paper a wall, with "cool" wall paper or do we paint and what color. Is that entry way going to be to dark,am I going to like it. Do we go ahead a paint the nursery that is now pink or do we wait till we actually are pregnant.What am I going to do the master bath in. All of this is stressing me out.
