The only one that I wrote was the doorway effect he's talking about task triggers and how when you walk through a doorway you tend to forget the thing that you were doing. He talks about cascading inboxes which in general I think are a bad idea however when it comes to ideas I don't think they're necessarily bad mention my five season creativity that depends on me capturing things to drafts and then eventually curating those sending them to obsidian but I think the way he describes them  I think this is dangerousYou want less inboxes in your life not more could be too much micro management. A whole bunch of tactical things as a result of that which yes I think these are dumb
