gtd

by .pQd
i like gtd, i’ve heard first time about the idea around 2006. since then i use some tiny-little-miniature form of it on daily basis; it boils down to writing things down, using reminders, tasks and todo lists. in other words – having OCD / being anal. i still manage to miss things, but in general ...
