する

する: the hand that makes things happen
The picture A hand reaching out and making something be the case. Only what appears changes. する is what a hand brings about; なる is what ends up being so with no hand in it.
Where the picture shows up in する
-
you make it happen
今日は残業します。
kyō wa zangyō shimasu
I'm working late today.
Sitting back down in an emptying office and spreading the files open again
-
it happens to your senses
変な音がします。
hen na oto ga shimasu
There's a strange sound.
A sound that wasn't there starting up on its own in a quiet room and reaching your ear
Sounds, smells and tastes する in Japanese — never 音があります.
-
it costs that much
このかばん、三万円もします。
kono kaban, sanman-en mo shimasu
This bag costs a full 30,000 yen.
A bag on the counter pulling 30,000 yen out of your wallet
-
you keep it on your body
今日はネクタイをしています。
kyō wa nekutai o shite imasu
I'm wearing a tie today.
A tie looped around your neck, knotted, and left hanging there
-
you settle on it
会議は三時にしましょう。
kaigi wa sanji ni shimashō
Let's make the meeting three o'clock.
Slotting the meeting into the empty three o'clock row of a schedule
All of it in one picture
する is one picture: a hand reaching out so that something not there before is now there. It starts the overtime in the emptying office, makes a sound appear in a quiet room, pulls 30,000 yen out of a wallet, leaves a tie hanging at your neck, and slots a meeting into an empty three o'clock row. All that changes is what gets brought into being — work, a sound, a price, how you're dressed, a plan. So with する the feeling is less 'I do it' than 'it comes to be, right there'.
