The impossibility of finishing things. 

I am convinced there are two types of people: those that finish things and those that don't.  Those that do finish things must have at one point finished something, and then they thought that wasn't so bad, let's keep on doing this.   They become successful, accomplished people even if what they produce is brilliant or just mediocre.  Those Magic Treehouse books remind me of this. A formula that works, now I know how to finish, let me keep producing! 

Some, like J.D. Salinger produce a few good things, but the pressure gets to them.  There, I did it.  Can I ever finish anything again?  I doubt it, so leave me alone. 

Many of us just produce and never finish.  Let me start something new, and I will never have to finish anything ever.  The never-ending novel blog-- a writer with conclusion block's dream.
