Anthony Joshua hopes to rule the heavyweight division for a decade as he prepares to defend his world titles against Carlos Takam in Cardiff.
The unbeaten 28-year-old will face Takam in front of 78,000 fans at the Principality Stadium in Cardiff, live on Sky Sports Box Office, and admits he is still improving as a world champion.
But Joshua believes he can enjoy a lengthy reign at the top, if he maintains his dedicated approach to the sport.
"I can't be perfect. I am who I am," Joshua told Sky Sports News. "I have managed to become heavyweight champion of the world and who I am, I can present myself as the person I am today, with a project and vision of improving myself for the future.
"Providing I stay disciplined in my sport, you'll hear of me for the next 10 years, and I'll definitely progress as a person, and that's what it's about.
"This isn't who I am today. I may make a mistake, but I'll correct it in the future, and that's what being a champion is about. If life was perfect and simple, people wouldn't be able to relate to me."
