Philosophy of a Traveller
A Traveller is a person who has had an epiphany, that what they have been doing with their lives so far is over and they have to head out on their own.
Their old career is gone, and the society they were part of no longer wants them in that role. Rather than lie down and wait for the end they break with their societal norms and begin to Travel. They adventure, seeking to gain rewards, rewards that actually matter: a sense of worth, money, reputation; not social status since they are now living outside their societal norms...
Remember what it says in the Final Word to referees:
“The players themselves have a burden almost equal to that of the referee: they must move, act, and travel in search of their own goals. The typical methods used in life by 20th century Terrans (thrift, dedication, and hard work) do not work in Traveller; instead, travellers must boldly plan and execute daring schemes for the acquisition of wealth and power.
Adventurous conduct, by its very nature, is not civilized. It is frequently not law-abiding either. Any world which is civilized enough to deserve the term also has a vested interest in suppressing adventurers, for the good of society. It is only on the fringe worlds, where there are neither enough people nor enough civilization, that "taking matters into your own hands" is routinely a viable strategy for dealing with problems.”
