In 1983, Dave Mustaine was fired from his band before recording their debut album. Vowing to start a bigger band, Mustaine eventually formed Megadeth which today is considered one of “the big four” of American thrash metal music. Megadeth has sold over 38 million albums in its career. Mustaine is regarded by many critics as one of the best guitarists of all time.
The problem is the band that Mustaine was kicked out of was Metallica. Which went on to sell 125 million records.
Mustaine set the goal to be a more successful band and it made him miserable that he never did. Why? Because he was measuring the wrong thing.
If all you measure is money or sales, you are going to make yourself miserable. There is always someone out there with a bigger number.
