Someone very wise once told me (picture this guy as Mr Feeny but with darker hair) that "your friends are a reflection of who you are." He actually said that in regards to the very woman I just got off the phone with. With every conversation I have with her, I am reminded of that quote. If she truly is a reflection of who I am and if I'm even half the person she is, I must be pretty awesome.
Call your best friend. Be reminded of the person they are and how that has shaped who YOU are. If you're like me, it'll remind you of how lucky you are and how well you've chosen the people you spend most of your time with.
