Smaller Is Better

"The smaller the object, the more forgiving we can be when it misbehaves." -John Maeda, "The Laws of Simplicity"

This quote was talking about real world objects, but I think it's doubly true for software objects. If we keep our objects small in our design (single responsbility), we will be more forgiving when errors arise. Why? Small objects are easy to test, debug, and well, fix. In fact, the fix is obvious because the object is so small. It's time to make our objects small and build layers of domain specific languages on top where each layer is simple to comprehend and understand. It would make our designs "more forgiving" to the ones who have to maintain it.
