If you have no money, then vegetate on your planet until the end of your own days. Well, or you can try your luck - go to war with strangers. Maybe you will be lucky and go back. Maybe even whole. Or go to the colonists. If you do not disappear in the first months, you will become a respected person in a new, developing world. Well, if you still have a little money, find an old trough, mistakenly called a spaceship, and go ahead for adventures. Welcome to the prospectors!
