Just a little bit more and it will be done.
Could we just add this and it will work then?
One small tweak and I think we can fix it.
We need to add another week, for the umpteenth week in a row.
Too often a project crosses the line and enters the never ending zone. And completion will seem so close there is just no reason to not keep pushing forward.
Except that the end never comes.
Time to draw a line, hit reset, and start over. And the sooner you make the hard call the sooner you get back on track.
Look at it this way. Say once in four times your decision is wrong and you hit reset when you didn't need to. The act of holding that discipline and being right the other three times will more than pay for what you lose on that one bad call.
