We bought a fixer-upper house, and gradually I became aware of the energy in the job. In particular, I identified:

1. the 80% slump, where the job is mostly done, but you are tired of the job and tired in body and mind. This is a good place for a friend to come along and help out.

2. the 95% shortcut. At this point, you are facing a deadline or have lost all enthusiasm, and you do something stingy or stupid that you always regret, just to get the job over.

When this time comes, it's best to down tools and get a good night's sleep.

It is easier not to fall into either of these traps if you remember their names and are aware of them ahead of time.

Joe, your pipes that had to be connected as darkness came on sound like a 95% shortcut.
