If you are going to start your own business, mind as well do something you love, so you are not looking forward a vacation every day!
Unless you are selling a product, don't expect to make money right away. I would suggest to do a bit of research. What is it that people need that will match with something that you love to do.
If you would like to earn money right away, I suggest going to taskrabbit.com - there they have lots of tasks you can do for people in your area ( not sure where you are, but unfortunately, they are not available in all the cities.)
I have 2 kids, so I work about 10 hours on my business.
If you love what you do, you will not be looking forward to a vacation. I would say give it a few years before your business can take off.
Hope this helps!
