Well, I've had full time assistants, and part-time students – one employee at a time – for over ten years. After my last assistant moved out of state a few years ago, I decided to go back to solo. It has been wonderful. It is a big weight off my shoulders. My workload also fluctuates and I could not ask my full-time mom-of-two not to come to work on slow days, so, scrambling to "create" tasks for her. It is a lot of responsibility, generating business to support another person or family. I now turn down jobs I can't handle (or do not really want) easily, my bottom line is not growing super fast, but the quality of life and peace of mind are totally worth it to me. Some employees bring their personal problems to work also (I had one who just needed to share everything as if we were friends – had to put a stop to that!).
Also to consider: you'll more than likely need an accountant or bookkeeper (unless you can do this yourself); be ready to pay vacation and sick time, and possibly health insurance, all do the paperwork those things involve. Not to discourage you, growing a business is very desirable, probably THE thing to do if you want to increase your income, and you can probably manage all those issues that proved less-than-ideal for me personally. Ha, you'll probably do it and find out it totally enriches you!
