A show that no one thought had a chance has just finished its fifth year: Charmed. I think it's tougher for the younger networks, so I think they have a little more patience for the sake of the show. But who knows?
Patience will benefit you in every hour, every time and every opportunity. It helps you to overcome your opponent, howsoever strong he may be. It will help you in times of distress and hardships, in battles and in war and peace.
The real test is not whether you avoid failure, because you won't. It's whether you let it harden or shame you into inaction, or whether you learn from it. . .
