hello. I am an 18 year old who is new to GTD. I have been reading up a storm, and the 43 folders site is a daily stop. I have created a sort-of lofi-hifi system, and was looking to hear what everyone thought. All input or suggestions are greatly appreciated.

My system is a joint effort between my laptop, treo, and planner. I will do my best to describe all their uses:

Laptop:
This is the home base. I run outlook to keep my contacts, email, and long-term calendar. It has due dates, events that are set in stone, meetings...things that are set. I also use onenote for some of my lists and all my research.

Treo:
This is for phone, im, sms, and having a mobile version of my calendar and contacts. I dont usually put calendar appointments right into it, for the options are limited. it runs onenore mobile so i can have some lists

Planner:
this is the main workhorse of my system It holds index cards, business cards, and post-its. The calendar part is a written tickler, which holds reminders of things i need to do, but only small items. More school related things. On the jr. sized legal pad i have a next action list of what i need to do that day. I also print off my todo (projects and bigger items) from outlook, along with a 2 week per page calender that has the big items. this area also acts like an inbox, with a pocket for notecards that have action items and for folded papers that i get.

So thats the system. Anyone have any ideas on how i can improve it? also, any ideas as to a replacement for the planner, as it is a cheap one and would need to be upgraded soon. GTD tips for a newbie also help. Thanks!!
