This is by far the best advice I've come across, a definite must-see for all creatives out there. Whether you're a writer, musician, artist, film maker or designer, it's such timeless and important advice to keep in mind.
I'm taking watercolour classes now, and it was really annoying at first to see how bad I was at it. But the advice from this video stuck in my mind, and encouraged me to keep going. Everyone is horrible at what they do at first. While it takes a lot of effort to push myself to start again after seeing the horrible stuff I've created, I do find myself improving with each attempt. I still have a long way to go before I reach the standard that I'd like to achieve, but I have to remind myself that growth and improvement takes time. And whenever I'm feeling unmotivated about my work, I can always rely on this video to pick me right back up!
