Mnemonic

A sunflower tracks the sun from dawn to dusk — no breaks, no complaints, just pure diligence. Where does it find the power to keep turning, day after day? That steady devotion IS its power. Every morning it clocks in, faithfully following the light like a tireless worker at their post.
Additional thoughts
Picture a sunflower as a dedicated employee, punching in at sunrise. Its constant turning requires real muscular power in its stem — that's the effort behind diligence. Sunflower + Power = the kanji for devoted, steady labor.
Quick recall
A sunflower uses all its power to track the sun daily with tireless diligence.
