This has really been the case with my Walden class this term. There were a few occasions when I got my work done early--particularly when I knew I would be unavailable on the day of the deadline. However, in most cases, I only get to work on the assignments on the night that they are due, often slipping in just before the deadline hit (which is 10pm in most cases).
This mentality won't cut it if I want to accomplish anything worthwhile with my dissertation.
