I'm secondary so some may not apply to primary 
Similar to someone else, if you have your own room (we do!) Have all of your PowerPoints/video clips/other resources opened at the start of the day to avoid having to try to find things mid lesson.
When the whole school calendar comes out, populate your diary with all key dates. Then you can work out where the pinch points are and plan for them.
Plan a couple of quick, easy meals for during the week when you are busy. There's nothing wrong with soup/sandwiches/beans on toast a couple of nights a week. It's cheaper than a takeaway.
Make sure your work clothes (and kids uniforms if you have kids) are washed/ironed/hung up at the weekend to avoid midweek clothes sorting!
Do as much feedback and marking in lessons as possible. Pre pandemic, I got really into 'live marking/feedback' and it made a huge difference to my workload.
I go through emails when I have time to action things -either replying/passing on/planning what needs doing.
Finally, remember, not every lesson has to be whizz bang! Sometimes, it's fine to keep it simple, use textbooks etc. Some of my best lessons have been the simple ones!
