Beat the refactoring blerch
View beat_the_refactoring_blerch
Have you seen Matthew Inman's (The Oatmeal) comic about why he runs? It's
a classic. In it he talks about his inspiration for taking up long-distance
running. He imagines his tendency to slack off and sit on the couch as a little
creature he calls "The Blerch". It follows him around, tempting him to stop
moving and scarf down junk food.
I run too, though nothing close to the distances Inman runs. In my experience,
refactoring as a skill has a lot in common with running or any other athletic
sport. You can exercise your refactoring muscles, by deliberately working
through the steps with discipline, like we talked about in the last email. As

You can’t perform that action at this time.
