Infinite – To-do list download (Monday Hour One)

I’m wanting to implement Monday Hour One, however when I start listing all the things I can do, it never seems to finish. I eventually stop. Then when trying to find time on my calendar, there is not enough time to put everything down. Thus, it never comes to a completion even in planning… maybe 20-25% of my list I find time for. Not sure how to make this practical and effective.
