Coders, write short methods! It helps with
* readability
* reusability
* and getting work done.

Readability

When you have many small methods and you name them well, your code reads like a paragraph. A well named method describes what the method will do. It's easier to read a series of phrases written in your own language than a series of math equations.

Reusability

A small method only does one thing. If a method does two things, you can only use it when both things should happen. If on only want one of the two things, you can't use that method. Methods should be Lego bricks not completed models.

Doing Work

Imagine you need to fix something in a long method. You need to understand the whole method before you change it. If you method is composed of many smaller methods, you can quickly read their names, then go to the relevant method and quickly understand it.

The computer does not care how long or short your methods are. Humans reading your code will thank you for using short methods with expressive names.
