Well said indeed.
I'm new to this business also and have assumed the mindset of vacuum cleaner. Upon completion of my professional
VO courses, if I haven't learned anything else, I've learned to "shut up and learn --- so I can speak up and earn" (Oh how I scare myself when I begin to wax poetic

)
Though I've been blessed (stress the blessed part) ... and am getting a real start with a three audio book deal (that is if the first is accepted well) ... that contract will ultimately be filled and I'll still be a rookie. So it's practice, practice, practice ..... listen, listen, listen .... learn, learn, learn ... until you turn off your mic for good.
Well there you have it ... all the 'sage' advice this rookie can muster.
