Right. There are also "forces" like management who want the project to be finished yesterday.
Another metaphor I like for programming is Chess. Any line you add to the program constrains its future development, becomes "weight" or "force" that pulls your development into some direction. Sometimes you have to sacrifice features like pawns. Sometimes you may sacrifice security, you may think it is secure enough. The outcome of this game is often a draw, or stalemate. And the same game can continue for years.
