It is in adversity that we find out who we are. Think about for that for a second, we will live thousands and thousands of days, but will truly remember only a handful. We will remember our highest highs and our lowest lows, but if life was easy we'd have neither.
As we continue to move forward and continue to succeed our work will continue to be challenging. The day we embrace the idea that there really is no finish line is the day we go from standing on the earth to holding it our hands.
