My To-Do Ordeal

I have gotten myself used to using calendars and To-Do lists for quite a while now after I have had believed that they are only beneficial to business men and such people.
I keep my use to a minimum, but they help me greatly.
It is said that great achievers all shared the use of To-Do lists.
The purpose of the To-Do list is to have some tasks in it. You simply aren't using it correctly if your list is empty.
My days pass with the list growing and shrinking. Well, until my semester's final exams commence. When that happens, the list starts growing and growing with not enough time for me to cross things out. Finals at where I study take two weeks, three weeks or sometimes even four. Stress builds up from the tests and the exponentially growing To-Do list.
My days start building up a depressing routine, fully draining me almost every single day with extreme lack of leisure time. My crave for fun and leisure manifest themselves as tasks that need to be done and find their way into my To-Do list, making it grow even larger, and building my stress even more.
I run through my list at the end of the day, finding it bigger than it was that same morning. I question each task, and wonder if I can just take it off the list. I contemplate taking off fun activities just to make the list smaller so that it would cause me less stress when I look at it. And eventually do.
The idea depresses me. Just thinking about it does, and reminds me of a verse that goes:
"3ukkazati heya na'6iri... hal fi jamad-n min na6'ar".
Said by a blind man, with him explaining his misery with blindness and how he suffers from it, the literal explanation of that specific verse goes something like:
"I rely on my cane to see. And how can a still object have vision?"
P.s. The main reason I wrote this note was to cross it out from my To-Do list, ironic.
