Would you ever open a business?

If so, what kind?

I've opened several businesses throughout my life. I opened a real estate investment company, I also had a graphics, illustrations and publishing business, I opened a network installation and consulting firm. Somewhere in between I had a bicycle repair business. They were all very profitable and I sold them for a nice gain except the bicycle business, I just gave it up and closed it. It was taking up too much of my time.

I was toying with opening up another investment firm, but my health took a turn for the worst. I am getting better, and the thought is popping back in my head. However, at this point in my life, I don't know if I want the stress. I basically don't do anything except remodel my house. Which was my intention of doing the rest of my life. Making this a showplace.
