I am an org-mode user myself, but I find the lack of inherent structure pretty paralysing and have built-up complex nested trees of tasks and org-roam notes that I haven't looked at in years. I fear org-agenda and the many year-long incomplete tasks I have been putting off.

I know this is probably not something that a tech tool will fix on its own, but do you mind sharing your config and how you converged to something that worked?
