After years of reading articles and doing a few of things I learned from those blog articles, I finally read the book. I can see how it all comes together for my personal tasks and projects. I started with Trello and now transitioned to Nirvana to track everything. I am getting comfortable with that and still working on recording everything as I think of it. Where I start to waiver is when it comes to the other inboxes that I am responsible for and how it can all come together. Besides the normal email, we have a help desk system (for internal customers), a customer service system (for external customers), and our team's project management system. These are all trusted systems themselves. My struggle is how to map all of this into GTD and where to manage those tasks. Obviously, I need to keep that task in the originating system, but I also want to make sure I know where that fits into everything else I need to do. I hope this makes sense. Based on what I read, I think these can all be treated as inboxes. What do I do with them after that? How do I categorize it? Maybe I'm overthinking it, but I am just trying to build an efficient system that I can learn and then share with the rest of team. Any thoughts or wisdom that can help me find my way?
