Want to Remember 1 - ER

I am a follower of ER, watched it being played at TVB Pearl for many years and I have kept "following" it. Finally, ER came to an end and while I was watching the "previously on ER" after the final season's finale, the following scene kept coming back to my mind from time to time:

It was the the final words that Mark Green told his daughter before he died:
"Generousity: be generous with your time, with your love and with your life."
