Ted Lasso (Jason Sudeikis’ motivational character in the hit Apple TV series of the same name) is famous for saying:

“You know what the happiest animal on earth is?  It’s a goldfish. Y’know why?  It’s got a ten-second memory.  Be a goldfish.”

Forget failure – it’s temporary anyway.  Why hold on to negative self-destructive thoughts when you can refocus on positive ones?
