An interpretation of that parable:
Amateurs think of equipment because they don't have any yet!
After the new gun smell wears off and dry firing/loading the empty mag into an empty gun/dropping the slide gets boring the thought occurs.. "maybe I should try shoot this thing. Let me find some boo-lits for my clip"
And experts: well, the arthritis puts a little damper on things. But my mind and my mouth still move pretty fast!
(note: NOT an expert...yet)
