Mnemonic

A crown atop your head and a rigid spine down your back — that's what it takes to operate a kingdom. The crown gives you authority; the spine gives you the backbone to manage everything without buckling under pressure.
Additional thoughts
Visualize the kanji: the crown sits on top, the spine runs straight down through the center. Operating any enterprise demands both authority from above and an unwavering backbone holding the whole structure together.
Quick recall
A crown for authority and a spine for backbone — everything you need to operate a kingdom.
