I used to teach undergrads on a Graphic Design BA and the most important piece of advice I could give my students was: don’t consume only creative work by your own peers, from your own industry, in order to feed your creativity.
Read, go to the theatre, look at art, listen to music. Create things outside of the commercial work you do. Be interested in architecture, science, politics, fashion. Stay curious. Keep sketchbooks. Take photos. Write things down. Have friends who think differently from you, who challenge you. Take your curiosity seriously. We live in the information age, we have access to so much…stuff.
It’s a smorgasbord. Fill your boots.
