My husband and two of our sons own a drywall company. I am their bookkeeper.
I also do a little internet marketing (selling nutritional and vitamin supplements on my own website) and I make more money doing that.
I cleaned houses for about 12 years. There was real money in that, but I just got too old to do such hard work. I was spending about half of my income on the chiropractor for my bad back. It's been soooo much better since I closed that business.
