My feet are hanging over the edge, so catch me

Why do i always give myself unnecessary stress? i'll have about a week or two to write a paper or do an assignment...yet, i'll still wait untill a day or two before it's due to even begin to write about it or even think about it. i dont know why i do this. maybe becuase i know that they are not going to be difficult to write so i just dont worry about it until it is absolutely necessary. i should really work on this and improve myself. every year i tell myself that i will: be more organized, be a better student and not procrastinate anymore. but it never lasts for more than a few days or a few weeks before i return to my wrongful ways.
