Also (or alternatively,) consider any you can make meaningful progress on before the Christmas rush sweeps in. That way, you will at least be able to resume progress next year without feeling too far behind.
A key part of this pre-review is browsing through your diary for undone sub-steps. These often come as a nasty surprise when you realise you’ve entirely overlooked important foundations for bigger projects. Therefore, it’s a good idea to eat and rest well before doing this EOCY preparation. I’m quite serious. It may send you into panic mode, so you need to be fortified. It’s not called EOCY!! for nothing.
Let panic & rationalisations wash over you for a moment. Then, calmly re-diarise the undone sub-steps into slots where you can truly get something done on them between those other slots where life frogmarches you forward.
Now get up and do the first thing you can do right now on your own plans.
