When you are extremely good at something there are things you do that no one else can help you with. It might be a matter of you having an expertise or some form of creativity that can’t be taught and it’s not easy to find others who can help you to do.
However, we all do other things that don’t require such expertise and which many others can do.
If you can insource (or outsource) the easier work to allow you to focus on the more difficult work your organization can get more work done, and everyone benefits.
Just a thought
Have a great day!
