You can see the difference between a chair made by hand by a carpenter who wanted to make the perfect chair and one made by a carpenter who wanted to get it over with.
Now on the other hand, you have two extreme ends:
1) The 'architect' who creates 4 layers of class hierarchies and factory-factories
2) And the guy who doesn't indent his code and types all of it in notepad.exe
I guess the key is to take pride and put thoughtfulness into what you do without losing sight of the fact that there's a end-user at the end who needs to use your work.
