The GM's job in any #ttrpg is to be an enabler for everyone at the table (physical, virtual or metaphorical) to have fun. If possible including themselves.
It is NOT to:
Make cool voices
Paint miniatures
Have a kicker music playlist
Know every single rule by heart
Build an expansive and coherent world
Craft an incredibly memorable plotline
These things may help in the goal, but they are NOT the goal.
