If you cannot delegate some of your work to make time for the bigger things, maybe you can find another way to share the burden with a group of peers in the same boat. It is not quite a support group in the traditional sense, but rather a group of people supporting each other's workload and strategic goals to make sure tasks are handled and the strategic actions happen.
For example, one writer connected with a group of professionals who are all working on books. Rather than hiring a staff of people for each of them, they split up some of the things they need to do, such as researching podcasts and radio shows for publicity opportunities or finding social media tools to help get their books out into the marketplace. It has reduced the burden on each of them individually, while helping them all do better overall and achieve their goals.
