Hi all ,
After reading most of the "getting things done " book , there is one thing that I don't really understand as far as Next actions are concerned.

Let's say that I have a project which is to mail some books to a friend of mine .So first I need to get her adress :this contains of an action of emailing her ,then waiting for her reply.
Then there's the action of packing the books [@home ] and then there's an "errands" type of action of going to the post office and mailing it.

What I can't figure out ,is whether I should have all those listed as next actions in their separate contexts ,for the same project ,at the same time -ort should I enter the first action,then complete it ,and only then add the next action to it's context? I mean ,in most cases there are numerous and dependent actions in a project ,which belong to different contexts,right?

I'm using the "nextaction" tracking tool for managing my next actions,and there's no way of defining dependency there -but the mail question is ,how is this supposed to work,the real-GTD way?

Thanks :)
