Of the many hard-earned lessons that came from September 11th, one of them is this: that life is precious, and life can be fleeting. Twenty-one years ago, nearly 3,000 voices were silenced on what seemed to be a routine Tuesday morning. So, today, take the appropriate time for remembrance and reflection -- but also leave room to embrace what you have. In a world where fear and division are in no short supply, make today about love and kindness, and take nothing for granted.
