If possible, spend your time doing what you do best. A doctor should spend their time providing medical care, not bookkeeping. A scientist should spend their time in research and not fundraising. An educator should spend their time working with kids and not doing paperwork.
Find a way to do what you do best. Also, find a way to let people who work for you do what they do best. Then provide support for those people to allow them to flourish.
Have a great day!
