Star Trek’s DeForest Kelley wanted to be
a doctor in real life, but he couldn’t
afford medical school. Later on, some of
his proudest moments as an actor were
the number of people who told him his
portrayal of Dr. McCoy inspired them to
become doctors. “You can win awards
and that sort of thing, but to influence
the youth of the country … is an award
that is not handed out by the industry.” Source Source 2
