Erik Spiekermann:

Every craft requires attention to detail. Whether you’re build­ing a bicy­cle, an engine, a table, a song, a type­face or a page: the details are not the details, they make the design. Con­cepts don’t have to be pixel-perfect, and even the fussi­est project starts with a rough sketch. But build­ing some­thing that will be used by other peo­ple, be they dri­vers, rid­ers, read­ers, lis­ten­ers – users every­where, it needs to be built as well as can be. Unless you are obsessed by what you’re doing, you will not be doing it well enough. Typog­ra­phy appears to require a lot of detail, but so does music, cook­ing, car­pen­try, not to men­tion brain surgery. Some­times only the experts know the dif­fer­ence, but if you want to be an expert at what you’re mak­ing, you will only be happy with the result when you’ve given it every­thing you have.

Being Obsessive About Detail Is Being Normal
