Here are my 2 favorite quotes from the Getting Things Done book.
They are the most memorable to me as they address issues at the CORE of what it takes to impliment GTD principals and to successfully GET ORGANIZED.
"Your mind if for having ideas, not holding them."
This may not seem a radical idea at first blush, but anyone who has tried to "keep everthing in their head" will know what a futile task this can be. If the only place you are tracking your commitments is in your head, you will likely be in a constant state worry and stress.
"Get stuff OUT OF YOUR HEAD, and into a TRUSTED SYSTEM."
Whether this is your first real effort at Getting Organized or an ongoing attempt to calm the chaos, we recommend this phrase become your mantra. To best apply the principals of GTD and "Get Organized", you will need to develop a TRUSTED SYSTEM for capturing all the "stuff" you have commited to do. If you don't find a way to capture all your commitments (big and small), you won't have a system you can trust.
I'll take the liberty here to modify David's quote just slightly....
"Get stuff out of your head and into a trusted SHARED system."
I add the word shared for two reasons.
1... It is rare that any of us are working alone to fulfill our commitments.
2... With today's technological advances, it is so much easier to find ways to collaborate with others it just makes sense to share.
Whether you are involved with a large team working on a complicated project or you simply need to coordinate a grocery list with your spouse, the ability to access a SHARED system can be immensly useful when trying to Get Organized.
