I should be up-front that I've never been the Undertaker's partner, but I do study career paths, so I will offer some advice here. The key thing I want to share is that you're looking at an extremely rare and extremely short-term job idea there. Literally a small handful of people would decide whether you get a role like that. Would they let you get into the WWE? Maybe if they thought you were the best person in the world for a role they were looking to fill! Smackdown Diva is one thing, but after a couple of year in that role, what would you move on to? But what you might want to consider more broadly is what a career in showbusiness might look like. For example, perhaps if you like being in the limelight and working physically, you could be a stuntwoman. You could consider acting. You might also want to work in theater or studio production, which puts you behind, rather than in front of the lights and the camera. All fun, and challenging, career fields!
So my advice to you is to keep holding up your dream, and at the same time broaden your horizons to accommodate more awesome dream careers as well.
