In your desire to please and impress them, do not go too far in displaying your talents or you might accomplish the opposite--inspire fear and insecurity.
Although your master may be proud of your accomplishments at first, once you receive enough attention and acclaim for your actions it is likely to cause your master to feel insecure about his own accomplishments and fear that he will be overthrown by you.
A great example of this can be seen in the story of Los Angelos math teacher Jaime Escalante, who was the inspiration for the movie Stand and Deliver as well as a best-selling novel following his teaching success. Despite his success he was later forced out of school districts by his administrations, more than likely caused by insecurity.
