It comes from reading Sal's posts history <3
You could always start writing a blog and start from it. I am currently writing a blog about Indie Music and I have to say, I have improved dramatcally in the past few years or so. The thing with blogging is that it improves your organisational skills when it comes to putting your thoughts into words. I can see that you do write a lot, and with a little writing here and there, I think you should be just fine!
Thanks farid, I don't know about blogging because I don't believe i'll attract an audience in this day and age where everyone is too busy. I may practice writing articles for my own sake though! Thanks buddy.
