Sorry I missed your lovely comment till now.
I agree with everything you say. Many times I burned the candle at both ends to get the project just right. Even when I was working on film sets I felt guilty if I left before any of the other crew. It is something I enjoy and am always afraid I'll miss something or be on my way home and be struck with a new idea that I then can't do. I believe professionalism in the arts is really important. It always leads to more work and collaboration.
