The book, which hits stands today, documents the singer's life, warts and all.
"I have owned up," the English singer-songwriter told ABC News of writing the memoir.
"I didn't think it's a bad thing that people see that I'm like everybody else," he said of that chapter of his life.
Collins, 65, says in writing the book, he realized how much he worked during the '80s, juggling rock band Genesis as drummer and lead singer, a solo career and collaborations with dozens of artists. Indeed, he spends a lot of the book apologizing for being inescapable that decade.
"There was that line in Entertainment Weekly, which said, 'Even Phil Collins must know we're growing weary of Phil Collins,'" he recalled. "So there was a backlash ... and … when I apologize, I'm really just saying, 'I understand why.'"
Collins also clarifies what he calls "Faxgate": the persistent rumor that he divorced his second wife, Jill, via fax.
"[It] really hurt my career, or my public persona," the musician admits. "And it was based on an untruth. … So, I just thought it would be an opportunity just to lay it all out, and if I say it didn't happen, I'm trusting that people will believe me."
While Collins says his ex-Genesis band mates and family haven't read the book yet, he hopes there's "a positive reaction."
"I think I've dealt with things quite delicately," he said. "When I messed up, I have owned up that this was my problem."
The Rock and Roll Hall of Famer recently announced he'll be touring for the first time in 10 years, and he just released "The Singles Collection," a three-CD set of all his hits, to go along with "Not Dead Yet."
