Working More is never the answer.
If you start working less, you will have to think really hard about what you will spend your time doing.
I've struggled with how to accomplish what I perceive I have to complete in a day with the amount of hours I have to complete it in. End result is I carry a lot of stress about what I am not getting done. I think the trick is figuring out what I need to accomplish, and what I need to let my team handle.
