Kelly Lester, a stay-at home Mom from California, had an interest in bento - the Japanese art of food packing. She also had an annoying problem every day: how to quickly and efficiently pack healthy lunches for her kids to bring to school.

A fish farm or fish based business could easily generate a good amount of money. Even if you are not a traditional fish farmer, you could easily make a steady income from your home, using aquaculture fish farming techniques. Fish is increasingly becoming popular as a source of protein, and it could easily feed a small family with very little cost or overheads. There are also other benefits of fish farming. You could use the waste from your kitchen to feed your fish, and if you have a kitchen garden, you could also use the waste from your fish as fertilizer for your kitchen garden.
Good ideas, I like numbers 2, 3, and 6 personally. I think in addition to persistence and determination, creating a successful home-based business also takes courage. It can be a scary proposition to quit your day job to go it alone. I always admire people who make this move, and I think that in general they are all the more happy for it. There is not doubt, though, that you have to go for it 100% in order to make it happen!
