Here's my interpretation. It's either gonna be 100% right, or way-off, but ah well, here goes:.
I think it's about someone rich & famous, and basically the love the person gets for being famous ("All I know is everybody loves me")means he doesn't care about anything else ("Don't need my health, got my name and got my wealth.")
The line "I lose track of time, so I might be past my prime" suggests a profession like an actor or musician, and I think the line "Get down, swaying to my own sound" seems to back up the latter.
