I've never had much success with digital todo lists, so I've never stoped using pen and paper to schedule what I have to do. On my current system I have a math notebook (A5 format) where I dump everything I have to do on the left (or right) non-writable areas of the page, and then everyday I write what I have to do for the next day on the writable area. I try to add for each day at least one of those items on the left/right side, and each day I try not to add more than 2/3 items per day. The reason that this works for me is that I try to have a very simple life, fulfill my daily obligations, and try to have as much free time as I can get. I do not need automatic systems to search my pending tasks way back in time because if those tasks don't "migrate" to the current page of the notebook, it's because they are not much relevant.
