What is your greatest weakness, and what are you doing to improve it?

"I believe my greatest weakness is that it is hard for me to stop working when there is more to do. I am very focused in my work and wish to complete all tasks by the end of each day. However, it isn't always possible to do so. To improve in that area, I do my best to prioritize and use daily to-do lists to keep track of my duties so that I can get to work as soon as I get to the office in the morning."
