If you believe you can review your list everyday, then your list is not large enough ;) Obviously, it would defeat the purpose to try to review it everyday -- classic quadratic algorithm -- nothing will be done and a lot of anxiety may be generated. If you are stuck and can't choose in a reasonable time, pick at random, and work on it: avoid multitasking (if it "maybe/someday" task, then you can afford it). If 1000 hours over 4 years is too much for your purposes, pick a different frequency -- having the habit should help either way. If there is no amount of time you are willing to reserve for your list than call it "Never" (that is fine -- as one data hoarder to another).
