I love using the Eisenhower Matrix to help prioritize when I have a ton of stuff to do (and a little time to write down my prioritization).
There is a helpful site I found about it here: https://www.developgoodhabits.com/eisenhower-matrix/
Basically, you categorize your tasks as urgent or not urgent, and important or not important. Tasks/items that are both urgent and important get done first; items that are important but *not* urgent, you plan for at a different time (in the near future); urgent but not important tasks you are supposed to delegate (hard to do when you’re home alone, so maybe alternate these with the important/urgent?); lastly, the not urgent and unimportant items you just say no to.
This isn’t a perfect system but I’ve found it really helpful when I’m feeling overwhelmed!
