Big E might be the most positive person on the planet -- the WWE Superstar was in amazing spirits while walking around and wearing a brace on Thursday ... just days after breaking his neck in a match.
E -- whose real name is Ettore Ewen -- shared how well his recovery is going in a video posted to social media ... saying, "I'm just here to provide a brief life update. I got breath in my lungs. It's a beautiful day. That's what's going on in my life."
The former champ said half-jokingly, although his neck may be broken, his heart is still intact .
