Richelle E. Goodrich said this quote

When you begin to care too much about what everyone else says, your confidence shrinks and you start to feel like insignificant, little Jack in a strange land of intimidating giants. But when you come to realize that opinions are as diverse and plentiful as dried beans, you might reach the conclusion that your own is of the greatest worth. That's when your confidence grows, and soon you find yourself striding like Gandalf the wondrous wizard among common hobbits in the shire. Respecting your own opinion is the magic that transforms both you and your world.
