Do You Want a Nine to Five Job?

Is it wrong to want a nine to 5 job and have your passions beside gigs? Why do so many songs have lines bragging about not having a nine to five job? I'm extremely exhausted from the lack of a daily routine in my class and rehearsal schedules. It's also really wonderful if you understand about yourself that you're someone who benefits from routine and structure, and that's where you thrive.
