"I'm sure you are. Starfleet out."
A role model was a person other people looked up to and attempted to pattern their lives after.
In 2370, when asked by Admiral Margaret Blackwell about the Captain Picard Day decorations visible in a communication with her, Picard nervously explained that as the captain of the USS Enterprise-D, he was a role model for the children aboard. Blackwell glared before replying, "I'm sure you are." (TNG: "The Pegasus")
Seven of Nine considered her mentor Captain Kathryn Janeway to be a role model in her endeavour to further explore her lost humanity; when she was taken captive and brought before Rudolph Ransom onboard the USS Equinox, Seven coldly declared that the man would be an inferior source of inspiration compared to Janeway.
