Writing is one of the few areas that will help you build residual income. Residual income is the income that is generated constantly from the work you have done in the past even when you don't work every day in the present. In other words, you will continue to earn in the present and future from the writings you have done in the past, without reworking on it.
How to build residual income by writing
Write and publish books
The generally accepted rule is you receive 20 percent royalties from your book. In other words, whenever your book sells you will receive at least 20 percent of the cover price. For a lot of professional writers, royalties are the main source of income. This 20 percent royalty rule applies everywhere in the traditional publishing house, as well as an online publishing platform. If you publish Kindle books, Amazon will give you uto 70 percent royalty. If you are a writer you should consider building residual income by publishing books.
Blogging
Bogging is another area that helps writers generate residual income. Your blogging will continue to earn for a long time. In fact, as long as your blog is live, you will be earning from your blog. How to make your blog successful is another topic of discussion.
Publishing on Article sites
Publishing on article sites also builds a residual income. I have a friend who is earning from hubpages, one of the reputed writing sites, from the articles he wrote in 2012. There are a lot of writing sites that you can try your hands for residual income.
