By that guy's "executing a day’s work" definition. Usually it's used in the same sense as medieval - early modern guild terminology: After having apprenticed with your first master you set out on a journey to learn further from other masters of the craft in other towns. (Hopefully to graduate to master yourself after a while. No intermediary "expert" step in those days.)
But maybe that's what you meant. Sarcasm is sometimes hard to detect online.
