Discipline has no value of it's own. It's a method, among others. There's no way to deduce from a perfectly orgamized garage weather it is because the oganizer had discipline or if he had fun.
I might not be able to tell if your garage is clean because you find cleaning to be fun, but there's a fair bet the inverse will be apparent.
1: Perhaps I should rephrase this as every activity for any person. At some point, you'll need to do something you don't find fun, and can't be gamified.
