"I think that I could be a little more organized and that I can balance my work and my life better. I tend to get very focused on the day-to-day work, and I lose sight of the bigger picture.

That way I can focus on my personal life once I leave work, which refreshes me for the next workday."
How you answer this could also determine where the interviewer would like to place you within the organization, or what areas of continued education/training they may require of you in the future. Again, even though this question has the ability to create a somewhat negative tone, you can still answer it in a positive way. Show that you are making steps towards improvement as well. Interviewers do not want to hear "I care too much." or "I work too hard." They want a genuine answer.
