So I've learned a few things from Getting Things Done:
1. Always have paper and writing utensil nearby at all times to prevent 'memory leaks.'
2. Don't procrastinate things that you need to do.
3. Be organized as possible.
Being able to defeat the urge of procrastination is key to your GTD setup in my humble opinion. Being organized helps you prevent your memory leaks. This is a very simple theory that I try to live by.
I have found you can incorporate a nice GTD-like system into your a notebook.
I have this system written down but I only have 1 question bothering me. I need subjects I can use to label certain parts of the notebook for easier use. I'm 18 and I plan on this notebook helping me out with life. What "subjects" should I use in my notebook. I've been coming up with a few like To Do List, Schedule, Want List, etc. I will label ONE page in my notebook with these "subjects" and use that page to organize information according to that subject. The remaining pages will be used for me to draw out projects and such. I'm also thinking I will need a subject that I can use to contain my sensitive information and a "Return if Lost" subject and such. Can you guys help me figure this out? THANKS!
