Where to start

I sit and look around our house and wonder what should I do first.....

Paint these white walls?

Buy curtains and blinds?

Contact someone about knocking down this wall? 

If the back steps?

Buy pavers for the grill to sit on so it doesn't have to sit right on the patio?

 Paint the front door?

Finish unpacking........

I just don't know what to do first.
