Simply plan your next day. That’s how I finished my app

This reminds me of another article from a while back which advocated 6 items in decreasing priority.

    1 -> big item
    2 -> medium item
    2 -> medium item
    3 -> small item
    3 -> small item
    3 -> small item

I can't remember anything specific enough to find it, though.

Either could be beneficial, and choosing only the next three at first may be a good way of forming a habit.
