It differs for everyone but I know that personally I must have things in order at home before embarking on any long hike (like over a week) or I just endlessly worry and my mind gets tied up in unproductive cycles while I walk ... all ... day ... long. It can be exhausting and uncomfortable to rehash off trail problems for hours on end as a solo hiker. Some people get on trail to escape off trail problems. I can't do that. Things have to be good off trail for me to enjoy being on trail. FWIW.
