Is this typical student behavior?

I have grown more aware that my perfect grade point average is slipping away slowly. Could this
be because I have stopped taking my classes seriously? Am I not putting
forth the effort to get the work done? The answer to both of these is
yes! But how do I make the necessary changes to complete assignments (on
time) and get the grades I've worked so hard to keep while in college? I
just looked at my grades for last week, and am appalled that I would
fall so fast. I love that my professor grades my essays with lots of red
marks; however, I do not like to see so many. I find myself hurt and
disgusted that I made an 85 on an essay that I could have easily made a
much better grade. This is what happens when I wait until the last
minute to do my work! I need motivation! After some online research I
found a site that should help. Household
notebook provides printable lists to help you complete tasks. I know
being more organized will be tremendously helpful, but is it enough?
No, I don't think just organizing my life is going to bring my
motivation back. My plan is simple...Everything is due by Tuesday night
at 11pm. Start my assignments on Wednesday before they are actually due!
This gives me a week to make them perfect and I don't have to endure
the stress of trying to turn in crappy work by the deadline. The
question is how to make myself do homework on Wednesday...
