This is being written a little over halfway through my trip. Boy, did I pack too much. I think because of Covid and being excited about finally traveling, I just got caught up in the moment and kept adding things. And I kept thinking that I will be gone a month so I will need more. And it's okay to pack more because I'm checking a bag (which I was). However, I forgot to account for all the train trips I was taking, and schlepping the bags up and down the stairs at the train station, and lugging them into a coach car. And so on...
My body was screaming at me and I was getting very stressed. So I went to Deutsche Post, bought a large box, packed it up with half my clothing, my sweater (it's been 80 degrees here), gifts I had bought, my poncho AND rain jacket (god knows why I brought both) but kept the umbrella, extra snacks (trail mix and nuts are HEAVY), my banana-shaped neck pillow (didn't help). 2 of the 3 pairs of reading glasses I brough (what was I thinking?), and my extra fold-up tote bag meant for gifts on the way back (there will be none because I'm mailing them). Oh, yeah, all my packing cubes - they just encouraged me to pack more, so they went into the box.
It cost me €50 and I don't regret a penny of it. Before anyone yells at me about the packing cubes, I will continue to use them but ONLY when I am stationary for awhile. Not when I'm relocating every 5th day.
For anyone packing now or in the near future, here is what I would suggest. Pack everything you want, including your purse, tote bag, anything like that, then pick up everything and walk about a half mile, then go inside and go up and down the stairs 2-3 times, then repeat. I guarantee you will stop and start removing things from your bag.
I have never done this before! Seriously, I prided myself on packing light. I don't know what came over me but I learned my lesson.
