When you are thinking about selling your business you might want to practice being less employed?
Have you considered only working part time in your business?
If you were only available part time, your employees could practice working without you being there all the time, hanging over them and giving them direction.
If your employees can work without you it helps dispel the idea that the business is really nothing but you and will increase the value to a potential buyer. Having more free time also will help you figure out what to do with yourself when you are not working all the time.
Working part time before you sell your business could be something for you to try.
