Some very interesting tips from game development that apply juts as well to general software development.
On code health:
Now I always try to dig right down to the root cause of a bug, even if a simple, and seemingly safe, patch is available. I want my code to be healthy. If you go to the doctor and tell him “it hurts when I do this,” then you expect him to find out why it hurts, and to fix that.
Though tools like SourceMonitor can help you track your code health, the best tool is between your ears.
