I don't think I suffer from a disorder like you seem to have, but I, too, can't keep any habit, regardless of my motivation. The most annoying 'habit' that I can't keep is sleeping. I never fall asleep and wake up at the same times. Trying too hard to setup a sleeping schedule only worsen the issue.
This is kind of frustrating when you see all those self-improvement books and people saying they 'achieve success' by twisting their will and forming the right habits.
I also use taskwarrior, this is really a wonderful to-do list manager. Along with Khal[0] to plan things (even if I can't stick to what I schedule, this is still stimulating to layout tasks in a calendar), it gives enough confidence to keep the head high and not sink under all the work that awaits me everyday.
The last sentence sum it up for me, these tools just help me to accumulate confidence and get things going.
