An actress may also be required to sing, dance, play instruments or other entertainment-related skills. The tasks and required skills of an actress may vary significantly depending on employer needs. Other performances do not have an audience and the feedback from these performances is not instant. The workplace is highly varied, and actors need to be flexible with regard to where they work and the type of environment they work in. Those prepared to work in all kinds of different situations and who are able to adapt to their different environments will be more successful in finding their niche.
