Code Is Read Far More Than It's Written

You write a line once.
It gets read a hundred times.

Mostly by someone tired.
Often by someone who isn't you.
Sometimes by you, who forgot.

Clever code flatters the author.
Clear code serves the reader.

Optimize for the second reading.
That's where the cost lives.

If they have to ask what it does,
it didn't do its job yet.
