Quality is in the subtleties. What we choose to do, and not to do. What we choose to include, the methods in which we do it, the material choices, construction methods, and systematic approaches in hindsight.
Restraint is knowing when and which ingredients to add and which ones to avoid, and we all need to learn to restrain ourselves from thinking we can do everything at once.
Restraint shows in the quality of our product, and it reflects right back in our professionalism and craftsmanship.
