If you want to keep growing your business you'll need to figure this out - unless you'll never take holidays, get sick, take an Fcar for some exercise.... Have you read the book E-Myth? Do you ever want to sell your business one day to retire or take some money off the table? Someone doing the job 80% as well as you could 100% of the time is often better than you doing 100% of the job 50% of the time. If that makes any sense. Congrats - great to see things going well for you!
