I used to do copywriting for a living before I moved into SEO and affiliate marketing. I really struggled, but some of the people I have writing for me are doing really well. I guess it's all about being able to land the contracts in the first place, which is something I always struggled with.
Yes, my brother used to work for few online companies, i must say he's doing this right and earning pretty gud. One of site he most work with is studentoffortune
Yes, you can. You can write for others and you can create your own site and monetize it. Many have done it and you can follow what the successful people have done. "Success is the refined study of the obvious."
With writing, we share our knowledge to others...not just for money only....i believe, a little knowledge may be useful for other..at some day..
Yeah, Feni is right! And if you could ever write just 1 book which is useful for anybody then you'll get enough money for living...
You can definitely earn a living writing content. I've been doing it full time for the past 2 years; you just have to find the right people to work for and stay active. It also helps to sell yourself to the client as a lot of people want some one whose confident in their abilities.
