Designers are not artists and vice versa. Some people still think of designers as ‘people who style’ objects and buildings. Although some designers might do such work (e.g. visual designers), they cannot be compared with artists. Here is why.
Artists have an innate, fundamental need to express their emotions, beliefs or views on the world (e.g. by means of a painting, graffiti or a sculpture). They use their art piece as a medium to express themselves and communicate their internal message with an audience.
Designers work exactly the other way around: rather than expressing and projecting their view or emotions on the world, they try to empathize with an audience in order to create sometimes that answers to their emotions, needs or beliefs.
Where artists create to express an emotion to others, designers create to answer to the emotion of others.
