One of the ways of getting afloat is writing content. All you need for it is some common sense, Internet and fluent English. You should not write articles for different portals, you should find an agency people order from and enlist there as a writer. Most of these have tests to determine if you can do things right and the best agencies have in-house training to make you a good writer.
General idea looks like that - You are given a task to write an article with "baby stroller" keyword, i.e. What do you know on the topic? Nearly 0 if you are not a breastfeeding mother (and just a little more if you are) . But God gave us brains and Sergey Brin gave us Google for a reason. Take the keyword you need to use and search for it. Read top 5-10 articles Google shows you in results - it will take no longer than 30 minutes. Then write your own while you remember what was written. With time and practice you will write decent articles, but rewriting top content will suffice for a start. Submit and article and get paid, and you can forget everything you just read about the strollers and begin working on new task.
Most popular topics will be dieting, healthy nutrition, weight loss & supplements, pregnancy advices, yoga for beginners and description of new mobile devices, according to my trusted friend who is earning for a living this way.
While you gain experience by writing on various topics, you will understand which of them appeal most for you. Try to concentrate on these, read popular content and guides from other writers\bloggers - and refine your style. With time you will become either a fast-writing pro for any niche or a specialized writer for a certain niche. Once your content becomes really good, either your agency will assign you to better projects or customers will find your contacts on their own and you will geet a freelance job which often becomes full-time - if you wish it.
This worked for many people I know and I do not see any reason it would not work for you. Patience, dedication and zero tolerance to procrastination. Well, these are needed in any business, so it applies to all cases.
Just don't apply for freelancer, elance, odesk or other portals like that. Indians with poor English roll there en masse and you will not be noticed in the crowd.
