On the one hand, you had a desired result: more of your heroes.
On the other hand, you had the result: failed attempts by compatriots to emulate the hero.
Maybe the problem wasn't that you had a hero, or too many non-heroes.
Maybe the problem was you.
The idea that everyone can perform the same way when given the same opportunity is local to you, the manager. Perhaps what you needed to do was recognise that some members of your team couldn't be the same kind of hero - but maybe there was another quest for them. Maybe the heroes you thought your were enabling by letting them follow the same schedule rules, really actually just needed you to let them be a different kind of hero: the kind that gets things done on a normal, 9-5, business-like schedule.

There is room for this experiment to be repeated.
