Fallback is important though; that is the "if I run out of money, seriously, then what do I do?"

There's a huge different between a $5/day lifestyle and a fallback to your parents basement vs a $5/day lifestyle and a fallback to, well, I guess I'll be living on the street.

The difference in cognitive load and stress between the two is staggering. Having a fallback is a very privileged position to be in.

Most entrepreneurs don't want to admit they can fallback to a parent's basement somewhere as it kind of kills their image.
