Stella likes getting things done. Note that this is subtly different from Getting Things Done. But if that's what gets you moving, Getting Things Done can help you on the path of getting things done. When you're cranking out ideas and then making them turn into stuff that people can use, you're doing what you're supposed to be doing.
When you're relabeling your file folders, maybe not so much.
Then I read this manifesto and I fell in love, just a little tiny bit. This is my favorite item in the manifesto:
The point of being done is not to finish but to get other things done.
And that's really it, don't you think? We can all sit around and sort our task lists, but really getting through what you need to today just frees you up for doing even more awesome stuff tomorrow. Or later this afternoon. Or whenever you are ready to move on to your next big idea.
