I haven't given the article the dedicated read that I intend to yet but my impression is that he does not expect to address all 133 items and it does not matter.

As someone who has compulsively accumulated lengthy to-do lists and buckled beneath the phantom of hopes and intentions of varying importance and ambition I find it enlightening that the possibility of completing a task other than those that are important enough to not have to write down to begin with can be measured by their meaningfulness and address according to this measure.

I gather that the .0050% of information that I consume daily is what is of the greatest priority and the remaining 99.995% is synthesized and iterated over the next day until it reemerges as something important. I suspect that Wiegley completes on average about 5 important things each day. This sounds like a solid baseline.
