I believe there's a fair amount of evidence that praising effort, not cleverness or 'being gifted', is much more productive for children in the long run.

Yes, this! Praise effort. Tell them it's okay to fail, heck it's even GREAT to fail because each failure puts you closer to success.

It's not a "You are talented or not". Sure some people start out with an advantage but everyone has to hone their skills through practice and effort.
