I have been writing for the sake of writing for most of my life; I've therefore put much of my life into honing the art of writing through classes, writing groups, and just plain practice. While I am strongest in fictional writing, I do run a Wordpress blog about writing tips and the occasional non sequitur topic and I have proven myself to be an excellent essay writer.
I love writing because while I may have intelligent thoughts, when speaking, my words often don't represent the original thought itself whereas with writing, I can take the time to put together the exact wording that expresses myself perfectly. I tend to be quite a bit funnier in writing than in speaking, if funny was my aim.
If I don't know something, I have the entire internet and a wealth of knowledgeable friends to help me find out quickly.
