I have started by creating an outline in Google Docs that I keep updated. This has all the elements of my world. It is pretty large so I won't list here. But it outlines everything about myself and what I am working on.
I run down this outline at least once per day and and see what has changed and what needs maintenance.
I am using Blogger to keep track of a lot of this and using it as part of the platform for tracking the data. It is one piece of how I use Google as a Content Platform.
I will keep refining this and posting my perspective of this.
