As an ADHDer, this is the story of my life. I'm using Dendron with PARA to organize the things I think about and do to keep them aligned. I review my 'Projects' to organize them within my 'Areas' or trim them and move on. The visual nature of Dendron.graph gives a decent approximation of the borders of my own knowledge tree, which gives me a idea of what others knowledge trees might look like so I can plan which questions to ask.
