To psychology, self-confidence is a belief in oneself. It becomes a mental attitude a person takes on of trusting or relying on themselves. Confidence is sometimes equated with freedom from doubt; however, confidence is needed usually when the outcome is uncertain. True confidence can then be defined as an actual feeling of comfort with some uncertainty regardless of what the outcome will be of a situation. Self-confidence is often linked with self-esteem. Artists such as Katy Perry, have a way of expressing ideas, such as self-confidence chosen in their songs. While both deal with confidence, "Firework" explains how to become confident while "Roar" gives a personal experience of self-confidence. .
In "Firework", Perry demonstrates how the person is trying to express themselves, but the other people do not care about it. An example in the song is, "Do you ever feel already buried deep six feet under? Scream but no one seems to hear a thing" ("Fireworks" Lines 5-6). In the song, the person is trying to demonstrate their feelings but nobody is listening to her, giving rise to the problem that can only be fixed through the strength of self-confidence. Another example in which Perry is still talking to the person and giving the strength so they do not give up is "Do you know that there's still a chance for you, 'Cause there's spark in you?" (Lines 7-8). This shows the audience the idea that the narrator is trying to express to the people that it is never too late to stand up for themselves. Therefore, it is never too late to show confidence in oneself that is what she is expressing, it is necessary to show confidence.
Although being oneself gives a blue-print of how to achieve a goal, this may help some people; however, others also need a real life example to demonstrate an idea. In the song "Roar", Perry gives her audience an example to achieve a state of self-confidence.
