My knowledge of the English language mostly came from being a wide reader; I read anything from novels, newspapers, magazines and even blogs. I've also been a call center representative for almost 5 years which means that I've been regularly engaged in English conversations for that amount of time as well. I'm not a profession writer but I have experiences in blogging since my high school years.
My knowledge in MS applications such as Word, Excel and Powerpoint were mostly based on self-study but my current job helps in further improving it through constant use.
