Humans are always required on distant planets. If you are not a specialist and do not want to become cannon fodder in wars with strangers, then the choice is simple: either you vegetate on Earth, working from dusk to dawn for a penny, or you fly to a new planet. There you have chances 50 to 50. If you are not lucky, you will die from fangs and claws of wild animals, or you will be killed by more successful colleagues. Well, if you are lucky, you will become quite a respectable and respected person in a new world under construction. The world that you also built.
