There are hundreds of online services where you can easily sell your things that are no longer in use. For example, if you’ve an old mobile phone handset lying useless in your drawer, you can sell it on eBay or Cragilist (oh, this Craiglist thing was really useful when I was living abroad!). If you’re in India you can use OLX and Quickr. These are free classified ad websites. Almost all of them have a mobile app as well. All this makes it pretty easy to convert old and useless stuff like CDs, books, clothes, stationary, toys into money.
Still, your options for earning money online aren’t limited to just part-time work and internet resale – and not even close. Thanks to innovative new technologies, the creativity of certain start-ups, and marketers’ eternal desire to better understand consumers, some websites will actually pay you just to use the internet – whether that’s for searching the web, taking surveys, or conducting extensive online research.
This isn’t to scare you off. I simply want you to know that this guide is going to focus solely on ways to make real, sustainable extra income online. Not just a few bucks. I want to share all the mistakes I've made that got me to where I am now so that you don’t have to go through them, and can build a successful online source of income for yourself.
