You become an apprentice when you lose your fear and start taking on the new and unknown with little hesitation.
As a journeyman you improve your chops, take some hard lessons and think there’s nothing you can’t fix or make.
Glimpsing mastery, you learn judgement. When you can improve something and when you should leave well enough alone. You become increasingly aware of all you don’t know. You recognize that mastery cannot be achieved, only approached.
I’m sure this applies elsewhere.
