The British fighter trains for bouts in the US with his coach Virgil Hunter and is willing to miss out on spending time with his loved ones as he has worked so hard to make it to the top in the sport.
Buatsi – who won an Olympic bronze medal at the Rio 2016 Games – told Boxing News magazine: "Making sacrifices is so natural that it's now become a lifestyle.
"If I explain the things I do, you'd be like, 'Oof, that's a big sacrifice, Josh.' But for me, it's normal.
"I'm away from family all the time; I miss a lot of celebrations. I don't get invites anywhere, because people will be like, 'Oh, yeah he's out of the country.'
"But (the sacrifices) have definitely been worth it. When I joined the Olympic team (in 2014), they said, 'Boxing's going to change your life.'
"I thought, 'How is me fighting or sparring that guy going to change my life?' I couldn't see it happening. But now, I can sit here and say that it's changed everything about my life."
Buatsi suffered his first career defeat to Callum Smith earlier this year and revealed that he got over the disappointment by climbing a mountain in Ethiopia to learn more about an ancient church called Abuna Yemata.
The light-heavyweight pugilist, who bounced back with victory over Zach Parker last weekend, said: "It was an amazing experience, something I was researching and looking into for months, so it was unreal that I actually got to do it.
"I wished that I could've been alone on that trip – doing it all by myself – and, when the guy picked me up, he was like, 'It's just you today', so I was excited.
"It's a memory that I'll hold forever, but I'll never go back to do that climb again."
Buatsi continued: "Going up was hard, but coming down was even harder.
"We hiked for about 20 minutes before the climb actually started, and while we were hiking, the geezer was like, 'Reserve your energy, because you'll need it for the climb.'
"I was already tired, and remember, there's no safety nets or harnesses. If you take one wrong step, you're not going to get injured – you're going to die."
