I was by myself, in a tent. When I felt lonely, I moved the tent closer to hiking trails. When I wanted to be alone, I moved it further away. The easiest way to meet people on a mountain is just walking to the summit and sitting there.
When I was tired of rice and beans, I hiked down to a little restaurant that had really, really good fried fish.
One time I built a hot tub.
A park ranger was kind enough to jump start my car when I was ready to leave for good. I feel like that was the least they could do after writing me six parking tickets, all of which I paid.
The rest of the answers, I leave to you.
