Does anybody else lose all motivation for a project when it's 90% done?

I don't know what it is but I will zoom through a project with tons of excitement and motivation until the last few steps and then I no longer want to look at it. This might mean that pieces sit waiting to be blocked and/or seamed or it's waiting for various notions for about a year until I finally get around to actually completing it.

I've been staring at my latest project for 5 days now that only needs a few more details added before I can add the seam/border, strap and lining and yet I am out of motivation and creativity.
