I don't know whether you have been following the story of the Spiderman musical. It has set a new record: the longest running preview on Broadway.
Because the opening night was postponed so often, some of the critics went ahead and reviewed the show anyway, and their judgments were not kind. Most of them agreed that the production is visually spectacular but the story doesn't flow well.
The original director, Julie Taymor, has now been replaced and a new playwright has been brought in to work on the book. Bono and The Edge have announced they are writing new songs.
The moral of the story: when it ain't working, it makes sense to make changes even if it's painful. From all reports, Julie Taymor insisted that everything was fine as it was and that's why she was forced out.
Sometimes we face the same decision in our own efforts and there's nobody to kick us out--except ourselves.
If you have a project that just refuses to work, it's worth considering whether more of the same will help or--more likely--you need to take a fresh look and be open to big changes.
It's difficult admit that what you've done so far isn't working and fire yourself (or at least the current incarnation of yourself), and make big changes but sometimes that's the only way forward.
Are there any aspects of your life where this might make sense?
