Protect Your Rubbish from the Harsh Critic in Your Head Another way we can make failure as cheap as possible for ourselves is simply to protect our rubbish from the harsh critic in our heads. Instead of shaming yourself for hitting your serve into the net, celebrate the fact that you’re on the court to begin with. Instead of belittling yourself for even the tiniest of errors, be proud of the fact that you are unlikely to make that same mistake ever again.
