It is great that you got married a couple years ago, but I am not sure where that fits into this discussion.

As far as starting your own business the best practice is to find something that you already love and/or are good at and figure out a way to build a business on that. If you have a hobby is there a way that you could sell items you make or train other people to do that thing?

If there isn't anything that you currently do and want to find something to get into, look around your area to see what people need. In Michigan in the winter a snow removal service might be a need, but I doubt that service is needed much in Florida!
