In between crops when you have time to think it through, create a packing list on your computer. Print it off each time you need it - leaving space to add items.

I never delete items from my computer list, just in case I will need it for the next crop and forget to add it later!

If you aren't going to take an item with you, just cross it off by hand.

My list includes: snacks, CHOCOLATE, favorite music, slippers, an extra pillow for my chair, and anything that makes me more comfortable.
