My experience is that those things you keep dragging to the next day again and again are one of the following:

* not actually important if you’ve been putting them off for a month * insanely important but complicated things that need to be broken down into smaller tasks * important things with a lot of emotional baggage attached; either hand these off to someone who will not have that, or make time to unpack that baggage - unpacking it is usually the harder option and likely to become its own constantly-deferred to-do.
