To me, the whole point of doing something like this is that there is no point. It matters, at the moment, to the guy doing it and that is all that matters.
A couple of years back, I rode my motorcycle for 18 hours with only fuel breaks. 8 hours of the ride was in 40+ degree Celsius heat and the next 10 hours I had to endure the monsoons. I loved the whole experience. What did I gain from it? In the grand scheme of things, nothing. Will I do it again? Yes, already planning another trip.
Life seems pointless to me. I just try to have some fun along the way.
