Career Dependency on Someone Else
Don’t make your own career depending solely on someone else’s career. Don’t feel like you have your foot firmly on the ladder just because you have a great working relationship with one director/company who’ll definitely hire you for every project he/she does.
It is a very comfortable situation not needing to aquire jobs because they keep coming in but media business careers are way too fragile and short-lived. What currently looks like a big and safe working relationship can quickly vanish into nothing when suddenly one of the movie/project of the director/company has no success or other unforseen things happen.
Build up a career and a network that is based on several important working contacts that allow you to compensate if one suddenly disappears.
