Gavin Aung Than, Zen Pencils, with a great comic that details common struggles of people who create things:
Before Zen Pencils, I had been making regular comics for at least five years. I was lucky enough to get a comic strip published in a local paper which required me to do one comic a week, every week of the year, for five years. Around 3 years ago, I got another comic published in a different paper. So for the last 3 years I was making two different comics a week. That’s roughly (52 x 5 = 260) + (52 x 3 = 156) 416 comics in the last five years on top of working my regular job BEFORE I had even thought of Zen Pencils. And I would say at least 200 of those comics are terrible and I would be embarrassed to show them to you.
So the best advice I can give to any young person, no matter what their pursuit: PUT IN THE WORK!
