Following on from yesterday, it's not enough to simply identify the one change worth making. The other improvements, the ones that will take up your time and energy without giving you the benefits. They are there, sitting, waiting, ready to pounce the moment you have some mental space.
No sooner have you put into action your big change than you start to realise the active part of that only takes a few minutes or hours. The benefit from from waiting and seeing that change go over days and weeks. You realise you have a lot of time before you see the impact, and you realise you still have a full recipe of small changes available.
Small changes that will demand your attention, and pull you onto them rather than making the small tweaks to your big change.
Keep the focus, keep the attention on the things that matter, and avoid the ones that don't.
