What Mantus said makes a lot of sense.
I too am a detail oriented person. You can tell just by looking at what threads I started and what I talked about
Regarding the day task calendar planner, it helps alot. If you are a person who is often in front of their computer like me, an electronic one is the best.
Not just one where you have to click on the program to remind yourself, but one that is in-your-face, thats overlayed over your desktop, so that those objectives you set always come straight into your face.
The program I use is called "Active Desktop Calendar". Try googling it. Its not free, but there are always ways around that...
