There are many ways to build you residual income and you already have most of what is needed. Most the needed stuff are your experience or what you are good it. Every thing else is not so difficult and can be done easily.

Now, Think of any one who did something and finished it and that thing is keeping earning him money. Any singer who made a song, clip are earning money from this song or clip through his life from sales at itunes, etc.. or from YouTube views. That's something you didn't think of. You thought that only business men are doing it. It is more than that. Celebrities are making money from recording themselves doing any stupid thing -like the ice bucket- and getting enormous YouTube views and $$$$

So, what are the types of residual income?

First, you can do your thing. You can make your product. Many people have done so. Many people have written their own book, CD, DVDs, Video tutorials or any other thing they are good at and built a site for that product then they got an Email listing service and put their product at affiliate network like CkickBank, Affiliate Junction, or Amazon. And they are enjoying the residual income and can even learn something new and make another product and multiply their passive income streams

Second, you can promote other people's products. It's better to choose a product with a recurring fees of course. But, you can do fine with a one-time-purchase-product. But how it is a residual income it I am promoting a one-time-purchase-product. If you wrote a good review for that product that ranked highly in search engines and got high organic traffic, it will convert sales to you while doing nothing.

I will list some ideas here as a list:

• Make your product
• Build a mobile phone app
• If you have a great idea, license it to existing company "get a Shark Tank deal :)"
• Make videos and put them on YouTube
• Create a content rich blog and put ads on it
• Sell your ads spots at your website at Fiverr
• Rent any rentable stuff you have

So, I want you to think if you have something you can make product of and write it down. Also, make a search online for ways to build a residual income and write the ones you can do or like.
