In my experience, successfully navigating the closure of a project is equal parts confidence and empathy. You have to be strong enough to let go, but also respect the psyche of the customer. Additionally, you cannot be too eager to wash your hands and disengage preemptively.
So why do I want to do this? Aside from the challenge, there are aspects of my previous water fast that I was not happy with. I also have curiosities about cycling into a ketonic state and want to try some new things out.
