Whatever it is you have never done before in your life and have no interest in doing, that’s probably what you’ll need to learn in order to keep your business running. Accounting, sales, inventory management. These are all things I’ve had to take on. These are also things that I would rather not do for the rest of my life. And while I’ll never be a crack accountant or a star salesman, it’s better to be mediocre than incompetent.
