The purpose of the list is to filter and focus. The list is that to which you give attention. If it's not on the list you say no, politely. The list drives you the proactive wolf rather than the hang-back sheep.
It therefore makes sense to spend just a little more time validating what gets on the list. The list is not a long notebook, it's not a jotter. The list is your flight-deck.
Decide your compass. Decide your goals. And hence what gets on the daily list.
