What are your best packing hacks?

I don’t go on many trips, but when I do, I like to pack early. In that way, I have more time to remember if I forgot to pack something. Another thing I like to do is to separate different sections for different items. Like one section for pants, one for shirts, one for clean clothes, etc. So, if I can’t see items in a particular section, then I may have forgotten to pack them. Finally, for items that I need to pack day of, such as toiletries, I put my toiletries bag on top of my suitcase to remind myself that I need to pack it.
