Is This a Good Idea for a Long Trip?

i usually think of like, what i'm missing in terms of things that might make packing or the trip easier. And then all i kind o look for that, um, like, china, fael, the void, whatever void you felt the last time you travelled exactly. I don't know why, like, it's so hard to get the baggage space thing just right. When i was going home, my carryon was just overflowing with stuff because i had went shopping,. and i just had a lot of stuff that i didn't prepare any extra space for.
