The 主 (Master / Candle) & 王 (King) Kanji Family: 主 (Main), 注 (Pour / Attention 注意), 王 & 理

Picture 主 as a tall brass candlestick (王) with a glowing flame dot at the top. Pouring water from a kettle spout onto a target is 注 (Pour / Attention 注意), and where a person sets their candle is 住 (Live)!

Look at 主 (Master / Main — omo / nushi / shu): it is simply 王 (King) with a single glowing flame dot (丶) on top! Add 氵 (Water) to the left of 主 and you get 注 (Pour / Attention — sosogu / chū).

5-Second Memory Summary: How to Never Mix Up 主 & 注 & 王 Again

Because 注 (sosogu / chū) means to pour water in a focused stream onto a single spot! When you 'pour (注) your mind (意)' onto one spot, you pay close 注意 (chūi — Attention / Caution)! And adding 亻 (Person) to 主 creates 住 (Live/Reside — 住む sumu).
