I believe that the goal of programming is to solve problems, not to produce code. If you can solve problems without writing code, so much the better.

The single biggest contribution to reliability, security and maintainability, is using less code to solve the problem.

Note: using, not writing. You may succeed in writing less code by using a one or more modules, but if the modules are over-engineered, too generic, grossly hierarchical, or otherwise verbose, then you can still end up with more code than you need. And that's bad all round.
