I actually believe that working long hours is a huge problem that obscures natural creativity in people. When you are spending hours in the same environment, it's difficult to have a breather and think about something original or new -- you need to have a proper break for that. Going for a long walk/hike, completely detaching from work, talking to other people about non-work related stuff usually gives me a perspective and organises and cleans my thoughts when I get back to working. Diversifying your pastime activities also may help in inciting creative thinking, just like meeting people with diverse backgrounds. It seems to me that you probably already have skill and knowledge, but it looks like you need more inspiration? Cutting down on your working hours won't make you dumb, but may just make you a bit happier.
