I have gradually eased back in to Bonsai after several months of non-use. I originally deleted it from my palm because I thought it was a lot of work to maintain. The truth was, I just had a LOT of stuff to track and no matter what system I used the amount of stuff was still the same. I love Bonsai because I tend to think and brainstorm in outline form and I can easily dump the contents of my brain into an outline. I find that I also tend to be more detailed with my projects and more specific with my next actions when using an outliner.
I have everything in one outline:
Level 1: Role
Level 2: Areas of Focus
Level 3: Goals
Level 4: Projects
Level 5: Next Actions
I use category color coding and also outline coloring during review time.
I use Bonsai mainly for weekly reviews, but I do check in with it every couple of days to update outlines and a few high priority projects. I setup some filters to make these mini-reviews easier to manage.
Everything from level 3 on down (since levels 1 and 2 have no time frame involved) to Datebk5 and use the datebk5 list view to manage the runway stuff and to check on due dates of projects and goals. I can also weigh the due dates against my calendar and see if I am spreading myself too thin. The two apps work seamlessly together. My categories are roles and my next actions start with a keyword to note their context. I also use the Bonsai tags in the notes of the tasks for easy jumping back and forth between the two apps.
I have dabbled with lots of 'methods' of doing GTD and I am finally nailing things down. I wish I had stayed with Bonsai when I first purchased it. It has really helped me to connect the runway with the big picture. Finding things in my outline is really simple because it flows. There are still a few rough edges, but it is getting better and better. Like I said - I eased back into it - one project at a time and built it back up slowly, weaning off my other system (pigpog). The transition over the last several weeks has gone well and I should have everything converted by this weekend. I can tell that this is the way I want to keep it because the more I work with it, the MORE I find I need to add to it. I thought my GTD system was complete, but I am discovering many cracks in the system and finding there were a lot of S/M items and other projects I hadn't even listed! Some of that stuff has been hanging around for years even. The more I empty my head, the more thoughts I have that need to get into the system. The flood of information I am writing down now is amazing. I think I may actually be approaching the mind like water stage - at a very rapid pace.
