Professionalism does not mean pretending to know everything. It means preparing carefully, communicating clearly, respecting boundaries, and being reliable about commitments you make.
The core idea
Read the actual brief and clarify ambiguity early. Arrive prepared for agreed sessions, treat crew and fellow actors with respect, and listen to direction as something to test.
How to apply it
Keep records of important communications and understand the role, schedule, location, compensation, rights, and deliverables before agreeing. Seek trusted or qualified guidance when terms are unclear.

Practise explaining a question or constraint in one respectful paragraph: state the issue, explain what you need to clarify, and ask a clear question without accusation.
