Good day!
With reference to your advertisement here, I am interested in applying for the article writer position.
I am confident that my qualifications, skills and past working experiences are relevant to the requirements of the position and I can make significant contributions to the continued success of your organization.
Also, I don't consider writing just as a job. Rather, I consider it as my passion. It's what I love to do and I'll make the most of any opportunity given to me. It gives me an opportunity to freely express myself. Because of which, I also make sure that my craft is of good quality and submitted on time.
Thank you for your time and consideration and looking forward to do business with you.
