Ubicumque antea nemo exii, audacter exire
To boldly go where no man has gone before.
This one needs more work. I'm having a devil of a time expressing the concept of "should" in Latin. But so far, here it is:
Ad Albuquerquensam sinistrorsum ire sciebam.
I knew I shoulda taken that left turn at Albuquerque.
Help with expressing these better would be appreciated.
