Here's some fairly common heuristics for you. Factor code out into subroutines when:

• You see sections of code that look nearly identical.
• You realize that some specific task your code performs is just a particular case of a more general task.
• You can imagine a scenario in which your code would be copied-and-pasted somewhere else.
• You can think of your code as performing a "black-box" transaction.
