It depends on what you are willing to do. One of the best proven ways of making money online without spending a penny or using affiliated programs is a blog. You can set up a wordpress or blogger blog for free. Customize it for free as well and wordpress has all kinds of free and easy plug ins that help you monatize your blog. Now this is not a get rich quick avenue but it is legit and there are lots of bloggers who earn 6 figures off of their blog.
If you don't want to be an Affiliate, do you have something you can sell online for example on Ebay? For example can you make jewellery, or you could find some unwanted items at home you could list and sell.
