Failure or not a Failure?

I've sent the starvation diet idea off to a group exhibition about failed art. I'm not really sure if this is failed art but thought that it threw up some interesting ideas about when and why we judge something failed.
The text from this is here:

Starvation Diet Failure Statement

“Starvation Diet” is an art/ life project based around food inequality. The premise was that I resisted food I didn’t need and gave the money saved to charity. The process was documented through, photography, film, text and currently resides on a blog site and a half finished book. As the project developed it involved others in “Starvation Diet, the next generation”, explored an idea called “Extreme Starvation Diet” generated a shared weighing scales element and resulted in my losing 2 stone and giving £367.00 to the charity practical action.

Why do I consider it a failed work?

The true nature of it as failure or success will only be evident at the moment of my death. The aim is to raise £10,000 in my lifetime and to remain at a healthy weight. The work is currently in a state of failure as I am putting on weight, have not donated in 3 months and have stopped noting the things I have resisted. The Next generation have not carried on with the project. The work is part of an effort to create slower art with less of a discernable end. This form of art brings up all sorts of issues around success and failure. At what date do we decide on a projects success and how does this choice of date skew this? When the lines between life and art blur are there more pit falls and less artistic control. As artists do we have the tenacity to stay with long term projects and not be distracted by new ideas and works.
