My Brain is full.
Like most people, I have to remember lots of stuff, I realize a lot of rubbish is in my head I'd like to purge (like the security code to a mcDonalds Store room I worked at in 1986 - 23609). I have used notes on paper, notepad, outlook all kinds of tools but none stuck.
I've been using my personal brain for about 3 months now and am hooked, I bought the professional version and use it every day. My only "nice to have" would be to have the brain database on a server so I can access it from anywhere, but I their brainEKP product seem to do that and since there is no price on the site I expect $$$. You can try the free version of personal brain and thats what got me hooked.
The tutorials and 101 class helped me get more out of it and understand what the brain does and doesn't do.
Once you "get it" its really easy to use which is why I use it, anything cumbersome would have gotten thrown to the side. I use it for contact info, project organization, software serial numbers, todo lists, grocery lists, how to's, links to websites etc. Its removed my dependency on emails to myself, todo lists and generally forgetting :)
Here is a screen shot of my "work" brain.
Go get yourself a extra brain, you'll thank me if you remember :)
Cheers,
Grant
