Are you going to be Simply Remembered Fondly or Actively Emulated?
I love Keith's definition of legacy too.
I recommend getting Keith's book It Starts With Passion. It would be a great read for you to begin to make 2014 the year of doing what you love and loving what you do.
Be the difference you want to see in the world.
