Martial artists would spend their entire childhood honing their fundamental martial skills while learning as many martial arts as possible, Arcane lords would spend years reading endless amounts of tomes and grimoires while beasts most likely spent days on end harmonising with nature and comprehending its flows and ebbs.
Even those who practiced the True Golden Path most likely spent years focusing on True Aether control before they ever began to cultivate.
This was his mistake—but at the same time, it wasn't necessarily his fault.
