You do the same thing you'd do on the AT -- or anywhere else that humans have explored over the last 2.5 *million* years.
1) You don't complain, whine, carp or quit.
2) You patently refuse to call Lyft and shuttle your way to a QuickieMart for $2 "bottled water."
3) You decline to fold up and die.
4) You look around you, and you use your head, and you deal with it. Same as on the AT.
(So, Step #1 is, you get out your map. And yes, Step #0 is, you carry one.)
