The Undertaker recently revealed that he has never been satisfied with his on-air persona, but it's not as negative a comment as it might sound.

A number of the top performers in the professional wrestling business have proved that the real key to longevity in the industry is to keep changing. Not completely, but to tweak aspects of your character and keep it fresh without overhauling it entirely. Tenured stars such as Chris Jericho and even Triple H are the masters of doing exactly that.

Even those two Superstars' abilities to keep themselves relevant dwarfs in comparison to The Undertaker's. Almost 30 years on from the character's debut and fans are still clamoring to see him today. We will get to again extremely soon too as he will wrestle the aforementioned Triple H later this week at WWE Super Show-Down. So how does he do it?

Well, in a recent out of character interview with Ed Young, which you can check out in full below, The Deadman revealed that he is "never satisfied" with his character in WWE, even after all of these years. Not because he doesn't think it was ever good enough, but because he has seen people in the business who are content with how much they've achieved, don't change anything, and they quickly fall by the wayside.

The Phenom listed a litany of big names that he has shared a locker room with over the decades, and discussed exactly why you can never be content in wrestling even if you're at the very top."If you kind of sit back and you know, check this out 'I just sold out Madison Square Garden.' You sit on that for a little bit, there's somebody else that's climbing that's like 'okay, I'm gonna sell it out five times in a row.'," Taker explained.

As The Undertaker has shown, those changes don't have to be drastic either. Aside from the brief period where he altered his character entirely towards the end of the Attitude Era, he has been the same person, but aspects of his persona have changed. Whether it be a costume tweak, a similar but improved entrance theme, or new moves in the ring. Clearly, it works, and nobody does it better than The Deadman.
