In my first university level programming course (I had been fiddeling a little around before that), the professor provided one guideline that I still think is great: A program should fit in a single page. Usually, it will be more than half a page, but never more than that. ("One page" was understood to be 60 code lines.)

You can't solve the program in 60 lines of Pascal, you say? OK, so make up another programming language in which you can solve the problem in 60 lines. Say, if an essential part of your solution is to sort a table of records backwards on the surname field, according to Swedish alphabetic sorting, then pretend that you have a language in which "sorting a table backwards on the surname field according to Swedish sorting rules" is a language primitive. When you have made a clean, readable solution in this hypothetical language, you go ahead to make another program by the same basic rules: One for doing that sorting...

I think this is a very good philosophical approach to code modularization: Make yourself a language that lets you solve the problem in 30-60 lines. Less than 30 lines provides so little detail that it is useless (like "void main(void) {solvetheproblem();}"). Make sure that the way the problem is solved is visible in the code! But don't bring in too many details; requiring more than 60 distinct operations (aka. code lines) indicates that you did not use the right language for the task. So make yourself a better suited language.

Obviously, these are main rules, not absolute. Some problems require less than 30 lines, and in any production setting you cannot expect library functions to suit your problem ideally, adding red tape. But as a way of thinking, it is a great approach: Every level of your code should add a significant, but not an excessive amount of detail. And, relate that stepwise detailing to the problem at hand, not to the libraries you use, language or other coding elements.

Even today I think this lesson, in my very first year of study to become a programmer, is one of the most valuable ones I has throughout my studies.
