Does This Job Application Make Me Look Negative?

The interviewer asked me to describe, in 1,000 characters or fewer, what makes me deserve this job.  I utilized 988 characters, according to their online count, as follows:

I'm passionate about non-profit organizations in this economy.  Passion drives great work. 

I don't need supervision.  I worked from home online for nearly three years to keep the bills paid without a full-time position, requiring keen focus.  I get the work done, and I'm a quality fanatic.

When you ask me to show up somewhere, I’m there.  I’m reliable, punctual, and disciplined.

I'm able to easily adapt to a variety of grammar constraints and writing styles to suit my customer.  I've done a lot more of this than my resume or LinkedIn profile will indicate.

I'm very comfortable with a variety of computer hardware and software.  I also have the ability to work around system bugs in newer software.

I've done some actual Search Engine Optimization work for the website that my husband and I developed for our small business (Lake Verona Lodge Bed and Breakfast) which helped increase traffic to our site.

Please contact me to find out more.  Your position sounds exciting!
