Quotes from Brian E. Becker

Armed with an awareness of how investors value intangibles,

At any given point in the life of a project, the only two things that matter are the amount of effort and resources required to complete the project, and the present value of the cash flows that the project will generate. As harsh as this may seem, the energy and effort already invested in the project are irrelevant. Goals and strategies change, and sometimes the most prudent course of action is to cut your losses and to move on to more value-creating projects.
