Personally, an internet business is an easy way to create a passive income because:

1. Require small to zero capital

2. Get started right away and easily

3. Work from home or anywhere in the world as long as there is an internet connection

4. Has unlimited potential to earn money

5. No age or education requirements

6. Doesn't have to have a company

What you need to do is to learn about the internet business as much as possible to discover whether it is for you and what your strategy is. There is free information around.  

Good luck.
