Set goals/progress milestones   I did when I built up there. Building up there was hard, and I  bought and built  no where near the off grid  desolation or acreage  your buying,  although when I started hitting milestones I knew I'd complete building my cabin and I knew it would be  a great place  for me and eventually my family for  taking  year round  vacations for extended periods(not as extended as I'd like  though) shh lol.   For example before I even started building 1st for me was replacing the existing submersible well pump and backwoods rigging a  water supply  to my old  camper  from well, also getting rid of a old uninhabitable snake and rodent infested  50' mobile home. Biggest milestone I recall wasn't when I stood up the 1st wall on my new cabin I was building but was when I stopped staying in my   camper and started staying in my unfinished cabin after I got one of the bathrooms somewhat operational.  Do  You have a camper?  but no way to get it out there  due to condition  of road? Is there a shorter  way in there maybe building a new shorter  road in,  right now sounds like your going to have to literally re build a mile long road that wasn't done right in the first place.   Like I kind of  said on a way earlier post when your property becomes hospitable to your standards hopefully you may  take great pride in what you accomplished.
