Act as if there is some value to the project...

To take from a much higher meaning message: we need to act as if there is some value to the project and find out that it doesn't than to act as if it doesn't have value and then later find out that it does. Sometimes (to often), project managers are not privy to all the information during the project selection/prioritization process takes place...we need to assume that those that are, are making the correct decisions and based on that, pursue the successful completion of the project as we would another project that we see as having clear value. Easy to say, but often difficult to stay motivated. The focus, in these situations, should be on performing out roles as best as possible, and trusting others...and learning, or trying to learn, there is a lot to learn in becoming a team player.
