Keep remembering that
The ending is not usually clear, even as you are approaching it.
Sometimes the beginning can help uncover the secret steps towards an ending.
important word in the the development process is "an" ending
it is the connotation of options...as in
this is one possibility...there are many more to be chosen from....
It's the ending for right now.
It can change for another version of the same work.
Most things do.
