Make sure you don't commit to two casting directors at the same time!
We have to all know that we are all lucky to be in this business in the first place. So obviously we get excited when we get called from a casting agency looking to book us for a gig. But when a casting director books you for let's say 3 days 2 weeks from now, you are booked with that agent. Do not double book with another agent if they want you for the same 3 days because "you would rather work on that project". You work on the one you committed on first and kindly say to the second agent"thank you but I am already booked those days, but please don't forget about me because I am interested." You will be respected and in this business it goes a long way, if you don't respect it that also goes a long way.
