Chris Brogan with some timeless advice that I always have to remind the perfectionist in myself:
Failure is a beautiful thing. It leads to more chances to try something new.
If you can, get failures churning along faster than not. The more failures you can get out of the way early in the process, the easier it will be to work past them, and then get onto a successful course. Failing very late in the process is a lot harder to fix.
One way to fail fast is to put out incomplete or prototype products or services. For instance, if you’re looking to sell your services as a social media consultant, don’t research all the various ways to do that. Put out an offering. Start trying to sell the offering. See how people react. See what works and what doesn’t.
If you’re looking for work, interview often. Learn what is useful in the interview and learn what gets overlooked. Learn how they react to different parts of the stories. The key part of failure is learning and adapting and moving on. The key part is what makes it okay to fail. If you fail all the time and don’t learn, that’s not all that useful.
