Why does it have to be nursing related?

I love this site. But I see most people posting are interested in starting a business that is health-care related. Why limit yourself? I know you are wanting to take advantage of your education, and there is certainly nothing wrong with starting a health-related business, but is that really what you love doing? Is there some other interest you have that you would love doing? Wouldn't you like to do something that you looked forward to doing when you get up in the morning? Something that really taps the creative juices within you?
My wife and I are both RN's and have been for many, many years. We recently started our own busines, she a candy store and I a tax preparation business. That may not sound like fun to you, but to us it's heaven. It's something that we both love doing and will be able to do for as long as we wish.
I hate to say, "Think outside the box," since it is a old and trite saying, but since I just said it...
