Failure is one of your surest paths to success in your career.
This may sound contradictory as success sounds like the path to success, but the painful if obvious truth is a lot of times we have to fail to get things right. We have to toss the old manuscript and rewrite, we have to learn a business idea is bad the hard we, we have to find out that our art skills aren't quite what we thought. If you want to succeed at your career, often times you have to try things and fail to learn what you're doing wrong (and doing right).
Fandom is an AWESOME place to fail.
