Dan,

you're not alone. Many of us have the recurring problem of taking a project so far, then not knowing how to tie up all the loose ends into a finished product.

For me this is true not only in music, but also in home improvement projects, raising the kids, fixing the car (etc etc the list is long.)

Everybody bogs down somewhere, but our bog down places are all different. Therefore I find it helpul to collaborate with others when I bog down. Almost always the other person will know a way to overcome my obstacles, and I will know a way to overcome theirs.

The forum here is an example of the same concept. All of us together are smarter than any of us individually.
