Great video showing Ira Glass talking about the importance of staying strong to your ‘good taste’ and about how it’s ok to admit it to yourself when you’re working on something just isn’t good enough. He talks about it in the context of radio and storytelling, but change a few words here and it could apply to any creative discipline.
It’s ok to be wrong every now and again as long as you recognise it’s wrong and are striving to be right, eventually you’ll get there.
The ability to recognise your work as being wrong and admitting it (if only to yourself) is as important as getting it right.
I recommend watching parts 1,2 and 4 of the interview too if you have the time.
