I have no reason to disagree with this date range . I would say no earlier than 2020 if for no other reason than to give this new real life Dyson Sphere and StarShot and SETI stuff some time to percolate through the realimaginary public consciousness . I read a very persuasive piece a while back that postulated our finalizing the existince of aliens will be almost a letdown because by the time we get around to proving their signal or life signs or whatever , we ' ll have been arguing about it for so long that we ' ll all be over it . <| sep |>. and I ' ve been to every gin joint in the world . <| sep |> Putting others first before yourself <| sep |> Looks good man , would make a good gift for a hunting friend . <| sep |> I ' m confused about # 4 . Depending on how you are interpreting gtd , next actions from all your projects are generally shown in an aggregate view on a task list . Most gtdsoftware interpretations are to just flag the next actions there could be more than one within each project so they then show up on the ' next action list '. Don ' t quite understand what you mean about most gtd software . What you are describing is assigning dependencies like you do with project management software MS Project , ety where you define successor , predecessor , concurrent , etc tasks when in planning mode so the software can automatically spit out the next defined step once you complete the predecessor . As a project management geek , I understand the appeal of that . You want to define the progression ONCE in planning mode instead of reevaluating what ' s next after every completed step . My Life Organized is the only personaltask manager that actually handles REAL dependencies more than just a subtask order like many others . True . True dependencies might be overkill but I always thought the idea of gtd was to show next actions you could really work on . At the very least for projects you should be able to only show sequential tasks eg show only the first undone task in the project which will be automatically replaced wth the next when done . It ' s surprising how many don ' t have this and yet charge . True dependencies like MLO offer even more of course . Pretty much any other system would enable a tagbased way of flagging next actions to show up on that filtered view . Don ' t quite get this . You mean most gtd software you have to manually flag the next task in a project to be active ?
