Why projects fail to meet the deadline:
The Wikipedia entry explains why this “Student Syndrome” is a good thing 
:
The student syndrome is defended by a layman’s understanding of the functioning of the human memory, most notably the concept that a person’s short-term memory fades over time, and thus studying at the last possible moment leads to better results than studying early because more of the material will be remembered during the exam.

I swear I am one of the best examples for the moment. Tomorrow I have an exam and 3 days I could not concentrate, I thought it was a lost cast. That was without taking the syndrome into account, this morning started at 7.30 and no way to get me out of concentration, accept this Blog I just heard of. Strange enough, cause I know the owner.
Thank you Student Syndrome.
