The British-Nigerian boxer suffered a second-straight defeat by Oleksandr Usyk in August, having lost his WBA, WBO, and IBF belts to the Ukrainian mastermind in September last year.
Speaking to DAZN, Joshua said: ‘My life is complicated. Boxing has become a bit complicated for me.
‘Everyone is just trying to make the most of this time while I’m boxing and they’re doing a good job.
‘But it does affect my ring activity. So I’m just always trying to push that stuff away. It’s a challenge. I’m just trying to get it out the way this year, so next year I can just focus.
‘I’m not champion and it’s just hurting a lot. So I’m in the gym rebuilding and restructuring everything I have to do inside and outside of the ring.
‘There is a lot that goes on outside the ring in my life which makes my ring life complicated.
‘So I just need to simplify a lot of stuff outside the ring and then I can put my full attention in the ring. And once I’ve got that done, next year I’ll be ready.’
He has since been linked with a potential fight against Deontay Wilder in 2023 – with Eddie Hearn confirming both parties have entered talks over a potential deal.
However, AJ has remained coy over his future. He said he doesn’t ‘want to make statements and then get held to the cross’.
He told DAZN: ‘I don’t know [when I’ll be back]. I was supposed to be in the ring this year, I’m going to be in the ring next year.
‘I’ll be in the ring when I’m in the ring. I don’t want to make statements today and then I’ll get held to the cross. Do you know what I mean? When I’m ready, I’ll be back in the ring.’
