IWSG~The Art of Not Going NUTS While Learning About Book Marketing

image creditAs I scan over this image, I see words I've never had to pay attention before. Pricing. Target, Market. I guess it hasn't been so much that I haven't paid them attention, but that I've avoided them. 
Thus #IWSG major fear - MARKETING. 
Now I know most authors have been in my position. Just sold your first book, thinking about edits, book cover, blurbs, etc... Not to mention you're pretty excited to dress, sparkle, and shine your first book baby.
But then your brain shifts. The reality gears between your ears begin to rotate and make an awful squealing noise. (Trust me, it's fingers-on-a-chalkboard worthy.) New questions form and coil into slithering eels of doubt that slink over all your gray matter.  
How will I enhance my website to promote my first release? What sort of games, gifts of services, and swag related to the story should I offer up? And then there's this monthly newsletter thing I can't avoid anymore. What do I include in that? How do I get folks interested enough to sign up to receive it?
What about the color palette for the book cover and image ideas I have? I'll need to prepare my dedication and acknowledgement pages soon - even those will tell people about me, who I am and what's important to me. Then there will be interviews. Promoting myself is as important as promoting my work. But I stink cheese doodles when it comes to talking about me. 
Holy make my head explode! I knew this would be a learning curve, but I fear I'll lose my sanity. Or what's left of it after having four kids.
How did you handle this stress? Any insight to offer?
