Not everyone gets to be an astronaut when they grow up.
As a bright-eyed kid, you once harbored dreams of a future in space. But face it, the only moon you’ll ever step foot on will belong to passed-out, drunken, former bright-eyed aspiring astronaut losers who are, unfortunately for you, your peers. Nice going, Buzz!

Because there's nothing standing between you and your goal but a total lack of talent and complete failure of will.
