How so? Some people need todo lists to keep them focused. Otherwise they forget things that they were supposed to get done, or allow themselves to get distracted by other things.

I use a todo list so I don't forget things. When I'm developing software, the ideas come faster than I can execute them, for one. But the list is only a vim buffer, so it would be hard to waste time micromanaging it like you can with more elaborate todo-list software.
