I used to be an avid GTD follower (David Allen's "Getting Things Done"). The book was an epiphany for me, but the whole system can be overwhelming. I now just use three text files (for work-related planning) for a Kanban-like system:

  * work due today
  * work due this week
  * work due this month or later

Every Monday, I pull work from the monthly list to this week's list. Then every day I pull work from this week's list to today's list. This allows me to focus on today, confident that I am not missing something. I can then ignore anything that doesn't need to be done until later. This is the theory, at least. ;-)

This is pretty good if you want an actual personal Kanban board: http://greggigon.github.io/my-personal-kanban/

I use it for my to-dos at work.

I spent a lot of time thinking about kanbans, only to realise org-mode can be very easily turned into one.

And IMHO an outliner is much more flexible than a webapp.

I also read David Allen's book and the one thing that stuck with me and made a significant difference was his two minute rule. If a task will take only a couple of minutes, just do it.
