There is an old saying that says "those who are heavenly minded are of no earthly good." Some Christians even think the sound of heavenly-mindedness sounds a bit extreme. For many, the idea of heaven seems nice and all, but it’s a concept that seems out of touch with reality.
Woody Allen once said that he couldn't stand two things: personally watching his own movies, and the thought that no one watched his movies. He stayed away from watching the final product because it was just unbearable to observe all the mistakes he had failed to correct. Yet, there was the hope that if he never saw them, they may not actually be there. But, what plagued him even more was the worry that no one would watch his work, or if they did, they would find each mistake he made and criticize them.
