“I'm sorry I wrote such a long letter. I did not have the time to write a short one.” - Abraham Lincoln
The point isnt to have less, its to have as little as possible required to perform the function you want, anything extra is just extra mental energy required to be able to understand it.
Have you ever written something and then vastly reduced it because you realise you are conveying the same thing in different ways, or written software and realised you have made 2 ways to do the same thing? thats all it means.
