Give a few examples of someone with high self-esteem?

Someone with a high self esteem might feel capable of doing anything. That makes the individual more confident (self esteem is often linked to self confidence)

1- When your teacher tells you that you are ahead of everyone else in your class, this makes you feel good about yourself and your self-esteem makes you want to continue to receive praise.

2- Someone who has just passed their driving test with ease may feel like they can drive a car straight after the result, this simply because their confidence has been promoted with the feedback from the instuctor, which means their self esteem has been promoted too.
