Whenever I'm reading interviews with designers and illustrators, I love when they get asked about advice for other designers. I was reading an interview with Shepard Fairey in issue 99 of Rock Sound Magazine, and I found his message of 'never give up' to be very inspiring:
"My advice is, if you stick to what you believe in long enough and keep making work, eventually it's gonna find an audience. People should always find an outlet for their artistic passion and make it happen on nights or weekends if they can't do it full-time. Never give up. Also, don't chase design and art world trends in order to try to succeed more quickly. You've got to just do what you believe in and then your day will come. No one ever gets anywhere or any respect for just jumping on art or design trends. There are a million Banksy copycats out there but there's still only one Banksy. I'm just too stubborn to give up, so it eventually had to work out for me. But it is totally hard."
