Is travel only for the rich ?

I often receive questions about my money. Sometimes people ask out of curiosity, but more often out of jealousy and hatred to me, as if I owed them something. I get accusations that “I must come from a wealthy family”, that I “might have robbed someone”, but also other ugly comments which edge over harassement. Nevertheless, I would like to explain how everyone can afford to travel, and I can assure you that this discipline is not only for the rich.
