Keisha is excited about trying out for the school musical because she has been taking singing lessons since first grade. Which factor is the best explanation for Keisha's intrinsic motivation?

Intrinsic motivation comes from enjoyment or interest within the person, rather than from outside rewards or approval. Keisha has taken singing lessons for years, so trying out lets her use an ability she has developed and likely enjoys. Wanting to impress friends or become famous would be external motives, while simply knowing about musicals does not explain her motivation.
