When you discover you are riding a dead horse, the best strategy is to dismount.
The worst strategy is to keep riding the dead horse, for nostalgia of its liveliness.
So what if the horse was once alive and breaming with vigor and strength? So what if the horse still looks healthy to onlookers? So what if the horse had a great reputation? If it’s dead, it’s dead. The best option is to dismount, get over the fact that it’s dead, and ride another horse (or a live mule if horses aren’t in the vicinity).
…The worst strategy is to fool yourself into believing that it’s still alive.
