12 Mark Greene Quotes From 'ER' That Should Be Motivational Posters

If I ever need a few precious words of wisdom, there is one TV character I happily turn to every time, and that character is ER 's Mark Greene. Dr. Greene was an old soul right from the start. I guess when your best friend is Doug Ross, you have no choice but to become an advice-dispensing machine. The world may never know how Mark honed his skills, but the man was like a walking motivational poster most of the time.

Now, just because Mark was wise in the ways of motivation does not mean he was always upbeat. His life had its share of tragedies, and as a result, he was not above handing out tough love when his colleagues needed it. Part of what made Mark such a great leader was his gift of knowing exactly what someone needed to hear. Whether he was talking Dr. John Carter down from a panic attack on his first day of work, or being the best dad he could be to his daughter Rachel, Mark always found the right words to say, even if the people in his life were not always open to his wisdom.
