My design philosophy revolves around the idea that good design is invisible. It isn't over the top, it doesn't catch your eye.
Designs should seamlessly integrate with the tasks of the user at hand so that they are able to move through each of their individual, unique experiences without distractions.
One of the ways that designers are different from artists is that, the things we create are made -for- people. Therefore, while visual aesthetic is critical to a product, it should always follow the path that its functionality lays out for it.
