However, I feel that, if an application is to be maintainable, it needs to be as decoupled as possible. To safely decouple something, you need to understand the business logic behind requirements. You need to be able to identify those things that seem to be popping up in the system with alarming regularity. You need to be able to identify those infrastructure features that would be really neat to have, but don't do add a single whit of functionality to the system as it stands. And, beyond all of that, you absolutely have to have the fire in your belly that makes you want to make it as beautiful as it can be.

If you're missing any of those things, don't read any further, cause what I'm going to say doesn't apply to you.
