learn and Earn by Paid Writing

[sayem001]

If maintaining a blog is difficult for you but you still want to indulge your passion for writing, you can jot down articles for other blogs or sites such as Weblogs, Helium or PayPerPost. Writing an e-book can also be a good option. E-books are investment free, with no cost for printing and shipping. If you have a strong command over languages, you can become a copy editor, where Webmasters will pay you to read articles and correct grammatical errors, sentence fragments, etc.

Also a good method for selling your ebooks, would be to write many articles marketing these ebooks to potential clients/customers. Fill these articles with links to your blog and there you go, niche traffic interested in purchasing ebooks that address their everyday needs.
