The traveller's first commandment

"The first commandment for every good explorer is that an expedition has two points: the point of departure and the point of arrival. If your intention is to make the second theoretical point coincide with the actual point of arrival, don’t think about the means — because the journey is a virtual space that finishes when it finishes, and there are as many means as there are different ways of ‘finishing.’ That is to say, the means are endless."

— Ernesto ‘Che’ Guevara
