At age 25, in 2002, I was the top salesperson in the country for Radio Disney. I was making great money. I was productive, successful and confident.

I was also cocky, arrogant, and disliked. I was downright unlikeable.

A year later, I appeared on national TV on the reality show Paradise Hotel, and promptly drank too much and totally humiliated myself in front of millions of people.

It took humiliation in order to teach me the virtue of humility. The thing is, no matter how smart, successful, good-looking or special you are, nobody likes a braggard. Nobody likes arrogance. Nobody likes cockiness.

It's really important to practice humility, to develop into a better leader and a better person. Humility and vulnerability make us more likeable. I have a long way to go still, but each day I remind myself just how small I am in the amazing, wondrous world around me, and that helps me to stay humble. Time with my kids, who don't care about my business success but just want to spend time with me- helps me to stay humble.

Inspirational quotes also help me a lot. Here are 15 of my favorite quotes that remind us of the importance of humility, in business and in life.
