Ask a guide who knows how to get where you are going. Easy enough. How do you know where you want to go? Compare and contrast destinations. These are two people providing answers to the same question. One person, Martin Parr is an established photographer known primarily to street photographers. The other, Marina Abromavitch was a major founder of a manner and means of expression. She is a creative with influence.
Martin Parr is talking to students at SCAD, a Georgia art-school founded in 1978.
Marina will make a piece of work; give you an exercise. It make make you uncomfortable. If it doesn’t, did it work?
Both of these people are talking to the young artist, not that person who gave up before getting thru their teens. Art has a way of being confused, as well as confusing.
Art is more difficult than knowing how to do something. It is not limited to doing something well, or important, or grand. It is a worldmaker, not a describer.
Learn enough in your twenties so you have enough time to have more than a career.
