What's really amazing is when seemingly unrelated stressful moments in your life are revealed to be from the same source.
Of course, this is probably a reason to do it.
Doing:
stuff I'm working on right now
ToDo:
Stuff that I know needs to get done
Done:
Stuff that is now done.
Start by dumping everything I'm thinking of in 'Todo' and pick one and put it in Doing and while I'm in the middle of doing it when I think thoughts like "oh and this should really do x" I add that to the Todo pile and go back to doing. Each time I finish of the 'Doing' task I scan the todo list, move anything I need to into Done and pull one up for the Doing pane.By externalizing the bookkeeping of all the things I'm trying to keep straight in my head I free up cycles to actually work on something.
As a result, I've started saving things less and less. However it's still useful to initially type them out. Helps me plan and form my thoughts and ideas. Currently this usually involves opening Textmate or Tumblr (and saving drafts) or email.
Hopefully this will be a solid replacement for all of the above. If I end up typing something I do want to use, then I'll copy and paste it elsewhere. The majority of the time I'll simply close the browser and not save it.
