I am also a naturally disorganized person. I was that kid whose grade school report cards repeatedly said "She would lose her head if it wasn't attached to her neck." So I know what you mean.
As this trait obviously doesn't work well for nursing school
. What I did this past term that worked pretty well is I put everything (and I do mean everything) I do in Outlook. Every reading assignment, project, study block everything was in Outlook by the end of week 2.
The appointments were put in the Calendar section and the various kinds of assignments were put in as tasks. I then put the day I wanted to do the assignment (or piece of assignment) as the start day and the day it was due as the due date. This meant that every morning at 8:00am a list for the day would pop up on my computer about what I needed to do that day. I also bought a Palm....the Palm talks to the Outlook, so everything that is on my Palm is in my Outlook and vice versa. This way, I have my calendar and To Do list in my pocket even if my laptop isn't with me.
All the above was fine....but it didn't help with the never-ending supply of paper and hand-outs we need to download and print. I'm lousy with managing paper....so, I work hard to have as little of it as possible. I use a tablet convertible computer, so I don't have to print out all the handouts for lab, I just use them on my tablet. I organize the handouts in a folder for each week and that way can find them pretty easily.
Hope some of this helps out some.
