The ex-guitarist of Metallica and the current frontman of Megadeth, Dave Mustaine has looked back on his past addiction issues and talked about the need to be honest with himself while admitting he thinks he should’ve been fired from both Metallica and Megadeth at that time.

During his latest appearance on SiriusXM, Mustaine has explained one of his striking confessions on his new book, ‘Rust in Peace: The Inside Story of the Megadeth Masterpiece,’ which was published on September 8, 2020.

Within the conversation, Dave Mustaine was asked what did he mean when he said he should’ve been kicked out of Metallica and Megadeth. Mustaine has opened up about the quote and said that everybody feels unnecessary sometimes.

Considered the period he was dealing with addiction problems and messing up so much, Dave Mustaine added that admission was born out of the need to be honest with himself, though it is one of the hardest things to think about as a musician.

‘Rust in Peace’, which was published by Hachette Books, details the making of Megadeth’s iconic record. Relayed by the lead vocalist and guitarist Dave Mustaine, the book covers the process of hiring the band and supporting cast, of trying to handle the ensuing success, and ultimately the pressure of fame and fortune, which caused the band to finally break-up.

At first, Dave Mustaine responded to the question about his quote, in which he said he should’ve been fired from Metallica and Megadeth, in the book with a joke that he just made that up. Then he talked about it and said:

“I think that if anybody has got to be honest with themselves, they’re gonna have some of those days. They will. You know you’re gonna have those days when you wake up and just think, ‘Man, I don’t know what anybody sees in what I’m doing. I don’t feel like I matter.’

You know, the typical days when you just end up working extra hard to get something done.”
