There are Many way to make money online but everybody are not resalable So, 

As todays business world becomes more and more web focused, creating passive income streams online should be one of your main focuses when building a business in the new economy – whether you’re doing this on your own, or with the help of virtual assistants that manage your blog, or even handle the marketing of your site – you’ve got to love making money while you sleep!

This doesn’t mean that (if you have one) you abandon your traditional business. It simply means that you can probably capitalize on the way that consumers are purchasing, more than you currently are.

If you’re a chiropractor, for example – why not create an eBook or audio guide on marketing and promoting your chiropractic clinic in your local area? You could then sell that to other chiropractors to help them grow their own practices.
