I use Evernote als a log for all correspondence, notes, checklists, clippings, articles etc. all sorted by creation time and tagged with relevant concepts. Then for every task I would ever like to do at some point in the future, from bucket lists type things to project tasks which aren't yet scheduled, I have a huge WorkFlowy list. Then for ToDo that I'be actually committed myself to I actually use Google Sheets where each mini-project has its own row with the next action defined and a history of all activities in the context of that project (both previous next actions and other things I did for that project) on the rest of the column. That allows me to keep a 'narrative' of each projects and to group them by meaningful time horizons (i.e. on a specific day this week, next week, the week after, the month after etc.) This sheet works really well for me together with some Keyboard Maestro macros and allowed me to grow my perfect system but it is definitely time for turning that into a proper app though. Whenever I get around to making that app I'd also love to include daily, weekly and monthly checklist/self-questionnaires/journals for additional level of planning structure.
