This is a question for any Indie publishers, or just Indie buffs out there:-
I think indie comics and indie products in general are largely labors of love that usually shine because of the effort and detail put into them. That being said, its a tough market out there and only a small piece of the pie will ever go to the indie publisher.
My question is for the Indie publishers out there: What is success for you? Is it crossing the line into mainstream? Breaking even? Just producing a quality product?
What keeps you up at 4am every night pounding away at your craft and when do you ease back and say, "Yes!" I've done it.
