I find TODO list (org-mode for me) useful when I have lots of small tasks that need doing, and I like that I have a record of what I've accomplished (good for when I have to write my performance evaluation). But for projects with bigger scope, I only do so in an adhoc way, e.g. as a comment in my code, reminding me to implement x, y or z. Systematizing my whole work life around a system? meh. more of a performance art than life hack.
