I would tell those people they’re not designers. Designers sell their work. Designers get up in front of people and explain why they’ve made the decisions they’ve made, and if you can’t do that, you can’t call yourself a designer. […] Being a designer has very little to do with being creative—you certainly need to have a core creative set, you need to have some talent, but apart from that, you need to be able to sell your work. You need to be able to solve problems and convince people you’ve actually solved that problem. ‘I want to sit here at my desk in front of my large iMac screen and my very expensive headphones on listening to my house music and cranking out beautifully layered Photoshop files that have absolutely nothing to do with this person’s business goals and call myself designer.’ I think ‘designers’ like that make other designers’ jobs a lot harder.
Monteiro nails it.
