I'm planning on leaving everything for a while due to a lot of things going wrong in life. Maybe a few months, maybe I get injured or figure things out after a few weeks. I have no plan, just a general idea of a direction and I plan on hiking trails but also just backpacking or hitchiking.

Do you have any tips on things that can easily be missed or forgotten while packing? I have some hiking experience but I've never been out for longer than three days.
