Confidence is known as the ability of a person to be confident without worrying about the impact or consequences of a particular action. Confident people are more likely to have creative ideas as well as express them as compared to people who lack basic confidence.
Confidence can help you put your best self forward when it comes to your creative ideas. People who are inherently confident usually express bolder and more creative ideas. On the other hand, people who are not inherently confident, shy away from such opportunities and tend to keep in the background.
These factors either suppress their creativity or keeps their ideas under the covers while confident people are more upfront about their creations.
