If you're the smartest person in your circle, then you need a new circle. I heard a wise man say, "A seed will only grow when it's planted in something bigger than itself." Are you planted in something bigger than you.... OR are you the smartest person in your circle? There's power in getting around people who are smarter than you, wiser than you, wealthier than you, more seasoned than you. Not only does it allow you to stretch to greater heights, it exposes you to an atmosphere that promotes transformation and growth. It can be a bit intimidating to for once NOT be the person with the most expertise or highest IQ, but get over it.  That's when you know you're in the right environment. Plant yourself in a place conducive to your growth.
