"...almost incredibly successful"

I picked up The Hitchhiker's Guide to the Galaxy last night and actually read through the introduction this time. And I found this gem:

"... Later I became a writer and worked on a lot of things that were almost incredibly successful but in fact just failed to see the light of day. Other writers will know what I mean. " - Douglas Adams

Do you have an almost incredibly successful project in the works? What stage is your future success at right now?
