Firstly get a hold of a large truck to put stuff in and fill it with canned and dry foods from a super market depot. After this I would find a nice property with solar panels, this would provide me with basic electricity all year around, maybe look to installing a wind turbine further down the line as well, the said property would have open fires for heating in the winter months. There are other properties with external oil and gas supplies that arent on the grid, so one of these could be inhabited. Once these basics were sorted, then look into acquiring weaponry, a petrol tanker and filling it before taking it back to the property. Once this was achieved, I could drive anywhere, in whatever car I wanted to gather anything I might need to amuse myself ie porn, games consoles and the like.
Yes it would be a bit boring but i'd more than manage.
