All successful projects die. The purpose of a project is to become irrelevant. Once it achieves the predetermined objectives, it ceases to exist. This is good.
Some projects die prematurely. They run out of time or money, or they fail to achieve the required quality criteria. This is bad.
Some projects are bad, but due to additional resources are artificially kept alive. We hope to improve quality or extend the time by flooding it with more money. This is ugly.
Like seeds, they must germinate to become more than the sum of their parts. We love it when new plants grow in their place. Sometimes, the environment is not conducive to germination. If you cannot control the environment, invest your energy into a new seed.
Death is inevitable. Accepting it is the first step to freedom from failure.
